It’s drumming, the multi-player game. The Drummer is an open-source application for the Nintendo DS handheld, developed by Andrea Bianchi and Woon Seung Yeo and presented alongside a paper earlier this year at the NIME Conference (The International Conference on New Interfaces for Musical Expression). As with any Nintendo homebrew software, you’ll need a special DS cartridge capable of loading software from flash memory – though if this app were developed more, it could make a terrific DSi app.

The idea is this: while making a handheld game system into an instrument, why not take advantage of its networking features? Grab a friend (or friends) with the Nintendo DS, whip up a drum kit that’s to your liking, then play along.

Oddly, while we live in a networked, Internet age, the client-server model rarely gets applied to music.
