OK not really one from The Rusty Chain but what to do? Build a bike or make an entertaining wee film using the bits lying around?
Created and animated by Tim Wheatley, the cyclotrope is a cycle of 18 images spinning at a certan speed so that the frame rate of the camera filming it gives the illusion of animation. To see more head over to Tim's blog at thecyclotrope.blogspot.com
Hope DH doesn't get any ideas...
