A Sky Hook is an impossible item that interns were traditionally sent out to buy , as a prank. These eight flying cranes, seven helicopters and one blimp, are as close to reality as sky hooks can get. The blimp proposal is actually named the Sky Hook.

Some of the most original or most innovative lighting ideas.

Famous French industrial designer, Roger Tallon recently died, leaving something of a design mystery. Newspapers universally credited him as the designer of the iconic French high speed train, the TGV, but that was almost certainly the work of Jacques Cooper. Tallon did take over from Cooper to do the TGV Atlantique, but this was an evolutionary rather than a revolutionary design. Perhaps Tallon's influence was more on the interiors? For me, Tallon's best work was his 1960's M400 spiral stair which seems to be the direct inspiration for some of Ross Lovegrove's best work.

The telescopes chosen for this list are largely based on how they look, from a design perspective, rather than their scientific importance. Their unusual requirements create interesting structural engineering approaches. However, the Holmdel Horn Antenna is possibly the most interesting from both points of view, its highly unusual shape is like a gigantic ear trumpet sticking out of a garden shed, but it also happens to be the device which discovered the cosmic microwave background radiation - the echo of the big bang. I've included a view beneath the mesh of the gigantic Arecibo dish, just because I always wondered what that space was like. For the rest I've chosen ones which best display the spiky, high tech look of giant scaffolds and space frames or which are attached in impossibly top heavy ways ancillary buildings, like the giant upturned umbrella of the Parkes telescope.

Ray guns originated in the US in the 30s, from shows like Buck Rogers. What makes them a particularly interesting object is that despite, for all practical purposes, having never existed, there is an almost endless variety of designs for toy ray guns, from around the world.Here are some of the best we could find. Most are for sale, and are posted without description, since the images speak for themselves.

There is a strange beauty to slow motion videos of car crash test dummies and airbag deployment, but these don't compare to the similar, but far more extreme safety measure of a fighter jet ejection. Here are videos of various aspects of their deployment testing and training. Some of these are absolutely mesmerizing.
