I don’t even know how to describe the Everyday Looper application for the iPhone. It lets you makes loops live and you sing along with them. I can’t sing along, but maybe you can.
Hmmm… Here’s a better description: Remember in elementary school when you sang “Row, Row, Row your boat” and someone else would chime in so they were singing the previous sentence at the same time? This seems like it would let you do that, but with yourself (and do it live). If you still don’t get it, just watch the video.

Looks like a complicated interface to learn but a very impressive video! I do not have this app but I thought it the video was very cool
