Community Project - Module ideas

[HyperNerd]

This thread is to discuss ideas for modules that could be integrated into the community project, and for people to post board designs.

I will kick start by suggesting a colour LCD module, so that graphics could be displayed on the robot, with all that annoying low level crap is taken care of by the module's onboard processor.
Also, with the addition of a (multi)touch screen, a GUI could be implemented.
(How about an SoR custom robot OS? But that's more for the software topic)
