I actually had to ride the bike quite a lot for debugging purposes ;D
I think i wrote something about Google earth (and Indiana Jones, riding to the moon) in the essay, but perhaps Google maps would be great also.
But for now I'd rather continue to explore new ideas, like making a solenoid drummer. Build that arduino monome (with shield).
If I where to continue with the bike build I thik I'd first do one or all of these things:
* hook the arduino up to a battery and save the data to eeprom (or whatever) (getting rid of the computer
* create a mount for my macbook in the bike
