here is a sketch i made after viewing a video of someone playing with small, real cubes, which were playing audio samples and then activating other cubes around. i just can't remember where i saw this video... have someone seen it? (edit: found it! thanks to jesusgollonet: http://www.tangiblesequencer.com/ by Jeffrey Traer Bernstein)

here is the sketch :

i'm working on the next version, which will hopefully provide more options, like the ability to load custom samples ;-)

thanks for your advice, i've taken it into account : links are now turned on at start, and signals/sensors are displayed by default when the user moves/rotates something. and samples are now launched by a double-click on a shape.

yes!! that's it! thanks a lot :-)))
