The original yellow submarine may have been aqualung inventor Jacques Cousteaus. Since The Beatles song, all manner of weird and wonderful, quixotic submarines have to be bright yellow, from home made subs, floating human powered septic tanks and deep sea exploration vehicles. Vote for your faves.

Want to see some more impressive glass stairs than those at the Apple Stores? Despite the fact that Apple actually has a patent on the glass stairs at some of its stores, their glass staircases are actually not all that innovative. The glass stair at the Carre D art in Nimes is more adventurous and was designed 20 years ago, and Ove Arup have engineered a purely glass stair with no steel fixings.

A gallery of products using radioactive materials.Because radiation was seen to be new and powerful, at the beginning of the 20th century radioactive material was used in products such as face creams, mineral water and medicine, by equating power with rejuvenation. For similar reasons it was even used in items from spark plugs to condoms. Although many of these items are from an age when the dangers of radiation were not known, radiation is obviously useful as a healing tool for cancer therapy, but it is still used in legal Chinese remedies, which are respected more because of their age rather than efficacy and quack homeopathic medicines which are tolerated while unproven, because they are harmless water.Vote on your fave examples.

In this kind of space, no one can hear you scream. Anechoic chambers use spiked walls to eliminate echoes, the end result might literally sound dull but the visual effect can be stunning, such as at the enormous anechoic hangar. Vote for your faves.

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.
