Autopia forums user AkamaiDetailing's DeLorean is a thing of beauty. As long as it can still reach 88 MPH, it'll be just fine.

Sobiepan, a Wroclaw Fine Arts Academy student whose last name means "his own master," said he was inspired by the elusive British graffiti artist known only as Banksy. His own painting is small, white and green, and partly uses swine leather to show a drooping acacia leaf.
On Dec. 10, Sobiepan put it up in a room with contemporary Polish art when a guard at the museum was looking the other way. Museum officials didn't notice the new painting for three days.
The fish out of water was identified as a remote-controlled, helium-filled shark that has topped must-have present lists this Christmas.
The 1.44-metre-long Air Swimmer toy has a radio receiver attached to its underside and can be operated by remote control over a range of 15m.
Designer-developer William Mark Corporation warns that the shark is for "strictly indoor use only".
A spokeswoman for air traffic control company Airways, Monica Davis, said a pilot had reported the shark and its location about nine kilometres from the airport at 2pm on December 26.
To make sure they were rarely seen from above, these planes were painted to fly just under cloud cover. Although the planes were ideally meant to fly at sunset and sunrise, when the clouds took on a pinkish hue and made the plane completely invisible against them, they were also useful during the day. Clouds are pinker than we give them credit for. We perceive them as white against the sky because the particles in the sky scatter blue light, sending some of it down towards us and letting us see the sky as blue. Clouds scatter every kind of light, and against the intense blue sky look whitish gray. But their color depends on what kind of light gets to them, and what they are floating next to.
Although we see the sky as a radiant blue, the particles are actually filtering out a lot of the blue light that gets down to the earth's surface. When the blue light is scattered, a good deal of it goes right back up into space, which is why the atmosphere of earth glows blue in some pictures. This filters out a good deal of the blue that gets to the clouds. The clouds scatter what they have, which is a spectrum of light with at least some of the blue filtered out, shifting the overall light ever so slightly towards red. Add to that the fact that the water droplets in clouds can diffract light at different angles, and the clouds are often rife with pastel shades of pink, orange, and green. They look white compared to a glowing blue sky, and a quick glance leaves people with the impression that they are white, but a long look should reveal this shifting, if minor, shades. A light pink plane is safer against them than anyone would expect.
My favorite section details how the British responded when it turned out they had a drastic shortage of binoculars, which at that time were very important for fighting the war. They turned to the world’s leading manufacturer of “precision optics,” namely Germany. The German War Office immediately supplied 8,000 to 10,000 binoculars to Britain, directly intended and designed for military use. Further orders consisted of many thousands more and the Germans told the British to examine the equipment they had been capturing, to figure out which orders they wished to place.
The Germans in turn demanded rubber from the British, which was needed for their war effort. It was delivered to Germany at the Swiss border.
The tactical advantage should be clear — the racer in the rear can make a sudden move when the front racer isn’t looking, catching the front racer flatfooted and therefore unable to catch up. But this advantage is moot if a cyclist believes he can simply outrace his opponent over the 1,000 meter course. That’s where aerodynamics come in. Vehicles in motion create slipstreams behind them — basically, rifts in the air similar to what a ship creates in the water. Other vehicles close behind them travel within this slipstream and get a benefit from it: they “draft” and experience less drag, and therefore need to expend less energy in order to go the same speed.
In the case of match sprints, this gives the trailing cyclist an enormous advantage. If the lead racer pushes it from the start, he will end up with only a slight lead with 200 or so meters to go — but his opponent will have much fresher legs. So in order to combat this, we get this weird do-si-do — on bicycles.
