Is there no limit to what you can make with Lego? Kyle Yeats and his friends at UC Berkeley put together this toilet paper folder out of Lego Mindstorms and a bit of scrap metal. It folds up a heaping helping of toilet paper for you, and then cuts it, conveniently delivering it to your hand and ready to wipe.
Short of having your own butt-washing toilet seat, this is the next best thing. But then, we never thought folding toilet paper was that difficult. Could be some great entertainment in the loo, especially if these guys would combine this idea with that iPod dock/toilet paper holder.
