This is a project called Block Jam about interactive music. We have series of tangible blocks and just by arranging the blocks we can simply rearrange musical sequences. Each block contains a sound group, and we can simply choose them in each block by dialling on its surface.
The idea is that it is meant to be really easy to make different polyrhythmic loops.
I would not say that it is an art tool.
Stop, play, rewind, you must be able to do more than that.
