Electroplankton is a new game on Nintendo DS. It was designed by Toshio Iwai, an interactive media artist from Japan. This is not a game, it is more an interactive and manipulative music and art activity. There isn't any objective to accomplish really, just exploratory play with color and sound. Children with high interest in in music and art could find this to be therapeutic and a behavior reward too. The drawback is that it is a Nintendo DS game rather than a computer game.

All the best!
