Saw a link to this amusing article on FB this morning. Back in 2009, Gianluca Gimini asked friends and strangers to draw pics of bicycles from memory. Some people did do a good job while the results from others were rather interesting. It's worth the read and there are 3D renderings of some of the more amusing/interesting pics.
