More hard ware

I've been talking to paul about which hardware to get for the floorstickies project (digit-stickies). Looks like we will get one very powerful projector for the floor and two more for tables (including on LED one). 

Also the Arduino's are turning up with the Xbee transmitters by the end of the month. 

I've left the mac mini running in the floor collecting sound but I have problems remotely connecting to it. Need to sort out a longer cable for the vibration sensor.
