The fixture they designed outputs over 800 lumens of focused LED lighting. It is controllable entirely over WiFi and is based around either an Arduino ( http://arduino.cc/ ) or a Maple ( http://leaflabs.com/devices/maple/ ) along with their open-source and open-hardware Light Shield ( http://saikoled.com/lightshield ). The firmware developed by these engineers uses the Open Sound Control ( http://www.opensoundcontrol.org/ ) protocol, a successor to the popular MIDI and DMX control schemes.
On the software side, the Saiko5 has fully open-source Python ( http://www.python.org/ ) example scripts which can be used as a backend to allow any software running on the computer to control the lights with simple commands such as "flash". At a higher level, they have also released an example audio analysis patch using the open-source version of Max/MSP known as PureData ( http://puredata.info/ ). The result is a variety of awesome videos showing the interaction of the LED light fixture with music which are posted at http://saikoled.com/applications/ .
The authors also posted a handy Instructable ( http://www.instructables.com/id/Ultra-bright-LED-Color-Changing-Spotlight-using-Op/ ) with step-by-step instructions for how to construct one of these light fixtures!
