Here is another design group. Much like funnel, only for these guys I'm actually gonna present one of their ... applications. It is called Visual Acoustics. It let's you, the user to make music using only your mouse. I don't quite know how to explain most of the things there. So just read this front page excerpt:

"Brushes are painted acros the screen, each consisting of an instrument and accomnapnying visual. The position of the mouse on screen determines which instrumental note the brush paints onto the screen."
