Christopher Andersson brought up the stribe, which is is an 8-channel multi-touch controller for music or video software.
and is partly based on monome 40h, which is a reconfigurable grid of sixty-four backlit buttons
. 40h and Stribe are open source.

Another gamestrument: http://bricktable.wordpress.com/about/what-is-roots/
What’s rad about this one is that many people can play at the same time.
