jorg pretz's binary clock

Jorg Pretz, a physicist from  Aachen University, has devised a binary clock that looks like a racked set of balls on a pool table.

The way that it works, is that when the balls are lit, they all symbolise different amounts of time. The top ball is 6 hours, the ones underneath are 2 hours each, the next three are 30 minutes each, the following five are 6 minutes each, and the ones in the bottom row are 1 minute each.

Therefore the time above would be 11.03. It lights red for am, and green for pm.

Much more awkward to read than a normal clock, but I want one!
