I need one of those "Blue Light Special" lights attached to my laptop.
Probably will need to develop an SDK for it..
A buddy has these Woot lights: https://www.woot.com/offers/usb-powered-woot-off-lights-6
Sadly, they only draw power from USB-- no controlling them in software.
(They got me a cheap laugh when I started singing "Turn on your Woot light..." to the tune of Neil Diamond's "Heartlight". Yeah, I'm a dad... >sigh<)
