My office had halogen spotlights that were too bright, hard to replace bulbs in, and looked horrible on video conferences. I found some cheap RGB LED strips on eBay, and things kind of snowballed from there.
2x 5050 SMD 5m RGB 150 LED strips @ $20 each
2x 6A 12VDC power supplies @ $12 each
2x breadboard power jacks from Sparkfun @$0.95
6x MOSFETs from Digikey @ $1 each
1x Netduino Plus @$60
100 lines of C# for the Netduino
100 lines of C# for the Outlook mail notifier
20 lines of AutoIt script for the IM notifier
Total ~$130 bucks for much improved lighting and some geek cred.
