John does this thing called glasbead. Glasbead is a multi-user persistant collaborative musical interface allowing players to manipulate and exchange sound sample files and create a myriad of soundscapes and rhythmic musical sequences. Current bandwidth allows as many as 20 people to play glasbead at the same time. The entire structure can be spun by flinging the ball at the core with a click and drag motion. Each "stem" can be flung individually around this core. The "bell" or "flower" stems each have a sample sound file attached (select a file in the list on the right, then right mouse click on a bell stem). when a hammer stem comes in contact with a bell stem, the sample plays. The volume of the sample can be set by spinning its ring (near the core, click and drag). The pitch of the sample can be set with the same ring, hold down the keyboard "Z" key.
