Yeah I don't know if I ever seen this done to an ibook before but looks pretty cool and is very easy to do. Just requires you to pop off the keys and taking a permanent marker and just coloring the "rim" on the bottom of the keys. I used a Lime Green color which gives it a kinda nice back-light feeling kinda glow. Hopefully I'll have a case to match this keyboard very soon I already changed the "sleep" LED with a green one. Can you say GreenBook?
