Japanese multimedia artist Toshio Iwai designed this bizarre musical experience for the Nintendo DS. You touch the tiny plankton to create harmonious tunes and, depending on the plankton, the kind of music you make will also change.
There are a number of different "plankton" game modes, each with their own musical experience. One of these includes recording sounds with the microphone and having them played back to you in different ways to music.
The US release was limited to online retailers and the Nintendo World store in New York. The Japanese release came packaged with a set of headphones.
Electroplankton Series (DSiWare)
A series of DSiWare releases, each one a single music utility taken from the packaged Nintendo DS title, Electroplankton.
Using the stylus or microphone, use the Electroplankton to make tunes or music. Each of the Electroplankton plays differently. There are no challenges, and each one is more like a musical instrument than a game.
When you select Beatnes, it starts by playing the Famicom Disk System "Disk Loading" fanfare before playing a song from an NES game on an endless loop. Press the SELECT button to cycle through the different sets of sounds.
