Here Is A Little Project,

for anyone with too much time on their hands,

 build a working model of a Greek myth featuring Sisyphus who was condemned to roll an immense boulder up a hill for eternity, but here is the thing, 

the working model is built from Lego, Jason Allemann of JK Brickworks designed this superb perpetual kinetic sculpture and for the more engineering-minded you can download a building guide and parts list from his website highlighted above, for we I will just watch the GIF (Graphics Interchange Format) at the top of the post.
