The other day, MM-er Alex Zalben showed us how to turn cups into iPod speakers.

YOROZU Audio takes that idea one step further:

That device will connect to anything and turn it into a speaker. It comes with the milk carton, but you can also connect it to cardboard boxes, window shades, suitcases, white boards, and--based on the diagram below--pieces of paper!

 Nifty.
