This is a nice homemade take on the Stimulo - by suspending cups from the lid of a cardboard box, this puzzle can be used for either fishing food out, or directly noshing from the cups! With some great videos too! Instructions available from the always handy-dandy Instructables website!

The Cat Powered Auto-Feeder
