To the left the main device with the two rotating led bars inside a blue transparent globe. Using Persistence Of Vision (POV) it shows as a perfectly stable text message. The message in the photo is just one of the examples. To the right the infared remote control used to setup the date/time, alarm time and messages (max 4).
Built-in is a backup battery that keeps the clock running overnight if you turn the device of.
The globe is sold under various brand names, e.g. Skytech and Nextech (or is it Nexttech?).

Plan

• figuring out the type of IR signal - frequency seems 39200 Hz
  
• identify the electronics inside and its specifics
• add some cool uses like message updates from the internet.

Interested? Join the mailinglist or the forum at the projects page and I'll inform you once something significant comes up. BTW these things seem to be around since 2004 so I am suprised I could not find any technical page about it.
