Michu shared his IKEA Expedit shelf RGB LED mod ExpeditInvaders. He connected 40 RGB LED modules and a keyboard to an Arduino to make a color changing Ikea bookcase:
I just finished my project “ExpeditInvaders”, a spiced up Ikea shelf! I added 40 LED modules to it and glued a keyboard on the bottom of the shelf. Now I can change the colorset or animation with my foot!
We don’t have an Expedit, but in the shop there’s about 10 Billies.

That looks so cool!
That is pretty neat. The (spectacularly ugly) Expedit line really lends itself to this sort of LED hack, almost so that I wonder what it would look like here..
