I'm looking to replicate this behavior via a plugin: http://www.joachim-breitner.de/blog/archives/239-gaim-thinklight-pidgin-blinklight.html
This should work for Windows7 x64, but ideally this would support other versions of Windows too so other people can enjoy it.
I'm mainly interested in this because I have a hearing impaired friend who uses Windows and this would help them quite a bit. I also think its a pretty cool feature and we both have thinkpads.

I'll start the bounty at $20. Might be easy, might be hard. I haven't ever coded so really don't know.
