I stumbled across this and thought it might be fun for some of the Csound crowd, perhaps?

It’s a Bluetooth midi controller inside a rubber ball that triggers by bouncing the ball. I imagine there could be some nice expressiveness when used together with Csound - both visual and auditive. I remember reading something on this list about an interactive sound experiment where children were given buttons that controlled different sonic parameters (don’t remember by whom... Art Hunkins? Tarmo perhaps?) so I thought this could be a fun revisit of that idea :-)
