I don't have really any wild ideas. I wanted to stick with more realistic ideas... I think EZRobot's idea to go with the EZbit connectors is a great idea. I'd personally would like to see you guys put together some sort of mega developers kit that would include various EZbit connectors, more servos, difference choice of wheels, etc... I'd also like to see some new robot designs and maybe some more types of EZ Bit connectors.
