Capture of a demo called "Numbers [party remix]" for OS X released at Sundown 2008 demoparty. The demo is made by myself (psonice), the music by m0d and remastered by beatslaughter.
The theme of the demo is the 'numbers broadcasts', mysterious shortwave radio stations that transmit random sounding series of numbers. It's widely believed that they are used by governments to communicate with spy networks, but nobody knows for sure and the governments aren't telling. It sounds a bit conspiracy-ish, but actually makes a lot of sense.
The demo was made in under 24 hours, while drinking beer at the party. It's done in Quartz Composer. You can get the actual demo from pouet.net:
