About this 3D model

Waves on your desktop! A 3D version of the Mechanical Pseudo Sin Wave thing, this thing emulates a 3D ripple in 8 bit format. And who wouldn't want that? Video of prototype is here: https://www.youtube.com/watch?v=LAEzt5Ofht0. Hand cranked version is available. Designed using Sketchup 8 and printed in PLA on a Makerbot Replicator 2 using Makerware 2.3.3.42 "Standard" settings. Build one and make some waves. Caveats: 1) Don't turn it upside down. 2) Does not work without 1g vertical.
