We had to design and build in 3D, 4 flies for an animation/tvc. Here's what they looked like as still objects before we animated. They each had to have a personality, though be all the same sort of fly, so couldn't deviate too much from the obvious features and colours. You can see the animation in the animation section of my web site; http://www.eadie.biz/motion-1/#/new-gallery-56/
