This thread is full of interesting ideas to stea- er... borrow for my arduino project. Keep em coming. ^_^

Already have the HUD and bar graphs figured out btw... Just a matter of the displays (7-segment, 16-segment, bar graph or otherwise), appropriate I2C LED display drivers and a few functions to communicate with them. Communication only takes up two I/O lines and is expandable a bit like USB. If there were some program storage space to spare (maybe go to an Atmega328 chip?), it could probably be tacked onto the MPGuino code.
