Add To The Music With An Online Communal Piano [1]
Multi Player Piano (www.multiplayerpiano.com [3]) is a bit of online musical fun. It's an electronic piano that you can play online via your web browser, using a mouse or keyboard. The novel twist is that anyone else who's looking at the web site can play it too, so you can join in with someone else's tune (or just marvel at the cacophony!).
A bit of interactive online fun for the kids, if nothing else.
