For source code of this clock: see http://git.luon.net/luon/wordclock.
Some ideas to do with this clock (in no particular order):
- Add wifi module
- Synchronize time with pc / ntp (see #1)
- Flash lights when you have an appointment in your Google agenda
- Adjust brightness based on calculated sunrise/sunset times http://www.codeproject.com/KB/cs/suntimes.aspx.
- fade words in/out
- blink leds (blink first led slow when it is 2:00:01, blink fast when it is 2:00:59; if it is 2:01:01: first led is solid, second led blinks slow)
