Powermac G5 Led Clock
This hack looks so cool that I am debating drilling little holes into my Powerbook's case so I can make a mobile version.
Gizmodo has the scoop on a LED clock hack for G5 towers put together by Swedish hacker Anders Lundberg. Unfortunately,
the instructions are all in Swedish, but from what I've been able to figure out so far, Nästa means Next and there are pictures. Have fun!
