A MakerBot TOM with attitude RGB leds controlled by the statu... Free 3D print model

This is an idea to implement a functional design into my bot using color fades to represent a status. I want to add some custom print codes so any help will be nice because I am pretty new into working with the MakerBot firmware, etc!

-Begin color -> to red (heating up)
-Red to Green fade (working, some extra effects maybe?, 2 or 3 steps between the print code)
-Green -> Light blue/blue (cooling, like the ABP cool down)
-Celebration colors now! :P and finally yellow or purple... or even XMAS mode, halloween mode, etc

Here is a demo of the current hardware (leds and controller). Next step is to decode the controler signals to link the arduino, then hack the firmware :)

My first attempt was adding a page up/down feature to the Gen4 interface and it works great in my machine ( github.com/makerbot/G3Firmware/pull/76/files ), also it will be nice if I can add folder and sorting support (a complete pcless -and snappy- operation)
