Top500.org have just released their updated list of the worlds most powerful supercomputers. In June all of the top 5 were in the US, now only 2 are, with India, Sweden and Germany appearing.Here's an interesting thing, you can make it into this list for less than the cost of a family house in Manhattan.The fact that a Swedish Military computer is at number 5 indicates that either the Swedish military require the world's most powerful computers, or they are just unusually unsecretive, and that there are many machines we don't know about.Here are the top 15, with pictures of the actual machines, where they have been built. Although the IBM Blue Gene has a simple and striking case, only the Barcelona Computer Center and Leibniz Rechenzentrum are contained in rooms that are at all impressive. Vote for which ones you think are worthy of note.

A gallery of incredible streamline design. No other period in product design is more important to American history than the Streamlined period. Here are our favorite gadgets and vehicles from the Sky Captain World of Tomorrow.Ironically the streamlined shape is less aerodynamic than it looks. It came from the high speed steam trains designed by people like Raymond Loewy or cars by Norman Bel Geddes (the father of the actress who played Miss Ellie in Dallas) and still exists in kitchen and bar-ware and the 40s style Airstream trailers which escorted the Astronauts off the Space Shuttle today and still look futuristic.

Until very recently, people still used the same principal that Newton had proposed, to derive latitude from the angle of the sun or stars at known times. The sextant (or originally octant) allowed people to do this relative to the horizon, rather than the instrument itself.Later versions of the sextant included a very simple version for emergency use, called the Bris sextant (not a great name for a device to be used on a rolling ship) and until the advent of GPS systems, bubble sextants were used on aircraft.

From a skyscraper's lights that can be controlled by passers by, to the legendary rock set design of Mark Fisher and Jonathan Park here are some examples of the worlds largest screens. Vote for your faves.

Halloweenerdy is a term often used to refer to costumes favored by geeks. These costumes appear at events such as Sci-Fi conventions, Burning man and, of course, Halloween. Halloween is like Burning Man but without the corrosive dust, a perfect excuse to spend three and a half thousand hours building a hollywood quality prop and to gawk at co-workers in marketing, wearing bondage gear.Here are our all time favorite costumes. Vote for yours.

The two cardboard box halloween outfit is a halloween icon. Why they are always funny, we're not sure, perhaps its the irony of the fact that they are cheap and low tech and without any organic curves. Here are some instruction of how to make your own: 1. Take 2 boxes. 2. Wear them.We not quite sure what to vote on here. Most iconic?

Before electricity, lighthouses relied on lamps that would almost be considered mood lighting by today's standards. Mechanisms were clockwork and had to be wound as often as every two hours. In the 19th century, Fresnel designed a lens that could focus this light into parallel rays and project it horizontally, dramatically improving lighthouses. By the end of the century, all lighthouses had Fresnel lenses classified into orders, with first order being the largest and most impressive.These days lighthouses use less elaborate lamps such as the beacons found at airfields, or even powerful, but unremarkable to look at, LEDs. Here is a list of some of the most beautiful and important lights ever made, including some 1st order beauties that stand 20 feet tall, and were floated on a mercury bed. There are no descriptions of each item, for this chart, as the images speak for themselves, however, the sites linked to have information about the lighthouses where they came from.

If you want to re-model your home in the style of an Apple store, here are links to the suppliers of the actual items they use.The designs of the Apple stores may not be particularly original in terms of architecture, however they break new boundaries in retail design with an attention to detail that is normally only found in major public buildings. The principal inspirations for Apple's interiors range from Norman Foster's Mediatheque in Nimes, with its central glass staircase and I.M. Pei's entrance to the Louvre which is the inspiration for the fifth avenue store. Although the cube itself (particularly when it was shrouded in black) is more like the Kaab at Mecca, proving that Apple is a religion after all.Many of the fittings they use, such as Erco lighting are used by people like Pei and Foster (where I used to work) and the exterior panels are made by the same firm that provided the panels for San Francisco's greatest modern building - the De Young Museum.

Included here are the RC helicopters that filmed New Orleans streets after Katrina, a seven foot Yodeling man and a remote controlled zombie for halloween. Vote for your fave.

The ability to print incredibly complex custom objects on demand through the use of computer-aided rapid prototyping techniques will transform product design.Here are some of the most amazing current examples of digital fabrication through techniques such as stereolithography, selective laser sintering, 3D printing and fused deposition modeling. Vote for your favorite.

As people blow each other to pieces, daily, on the planet below, the silently floating Hubble telescope seems to represent everything great about humankind. Here are our other favorite telescopes.Update: Have been in continuous operation since 1963, the Arecibo project is in danger of closing due to cuts in funding. Jonathan, who is a researcher working at the Arecibo dish has posted a link in the comments to its website where you can donate or voice your support. http://www.arecibo-observatory.org

The Oobject Rotten Apple Award. To mark this week's 10th anniversary of the death of the Newton we have picked some of the products from Apple, that we'd rather forget.We could have picked many more from the years when Jobs was in the wilderness and Apple attempted to be market driven rather than design driven, under Sculley. Reactive rather than pro-active. One problem, the gallery would have been a sea of similar, anonymous items. For the Sculley era machines, assume that we mean every product in the range.(update: Apple's earnings are just in and they are blow-out. After hours trading shows that as of today, Apple is worth more than IBM.).Vote for your all time worst product.

For sheer baroque complexity of appearance, planetarium projectors are among the most amazing gizmos ever built. They range from enormous machines more than 20 ft. high to a soccer ball sized $300 home version.Their purpose is a bizarre reversal of a large optical telescope, taking an internal view of the the universe and projecting it on a dome, rather than creating a view from peering outside of one, but the aesthetic is somewhat similar. Another curious similarity is how much they look like some early satellites.Our personal favorites are the original Zeiss, Mark I and the truly amazing machine built by the Korkosz brothers for the, appropriately named, Seymour Planetarium.

At first glance you think, wow a tie camera, a camera in a case, mirror, plant, cigarette packet, cell phone. How cool would that have been when I was a kid? Then you think, hmm …cell phone. Cell phones already have cameras, its a pretty dumb place to put a spy cam.The progress of technology has overtaken the mystique of the hidden camera such that we have been invaded by a million spy cams embedded in wholesale crap.Vote for the silliest. Oh, and do check out the rather great antique watch camera which is from the days when spy cams were actually impressive.

Singapore Airlines has this week banished the mile high club, with the introduction of on board double beds. The rest of the interior, however is fairly bland. Here is a list of some of the best aircraft interiors.

Quite often a company will release a limited edition item to mark a product's anniversary that is actually worse than the original. We trawled the web to find examples of well designed anniversary gadgets, including our favorite, the 300lb limited edition espresso machine that was used by the Pope. Vote on your favorite.

Acrylic cases, cut aways and even solid glass mechanisms, allow for transparent enclosures where you can see the intricate workings of a machine.This tradition of 'skeleton' cases comes from watch making, but there are versions of everything from Nikon cameras to cars that show off their innards. In putting together this collection we were trying to imagine if you could have a fully glass house (several have been designed, none built) where every item in it was as translucent as possible. Vote for your faves and recommend any we can add.

Diving helmets are beautiful objects. Here are our favorites from modern versions with amazing visors for undersea welding, to incredible Steampunk style ones that look more other worldly than something from Jules Verne.

What passes for interactive clothing often consists of a button to control your iPod from your sleeve.Here is a roundup of some more interesting interactive clothing ideas, including a jacket whose fur stands on end like a scared cat, a bikini whose breast pads inflate as a life saver and a jacket with a digital organism that grows as you wear it. These are alongside some more serious ideas such as a medical monitoring clothing and a robotic jacket to aid the paralyzed. Some are fairly well known, but others are hopefully new to you.

Our favorite lights based purely upon aesthetics. Vote for your favorites.

The stuffed chick with light bulb, understandably caused some fuss when it was created. Other strange lights here include pear lights which can be plucked out of a tree, paper plane lights lights that look like water dripping out of a tap and a lamp from a spinal column cast.
