Nathan Sawaya, Lego artist extraordinaire, has made a fully functional cello out of Legos.

I built a cello out of LEGO. It is the actual size of a non-LEGO cello. It also sounds different from a non-LEGO cello. Here's the YouTube video that everyone is talking about of me creating the cello brick by brick.

Nathan, if you’re reading this (you probably aren’t), I challenge you to make a full blown double bass. Mwahahahaha.
