Carl Erickson from Phenostream has built a very small yet very smart stepper motor. Many of them can be controlled via a daisy chained serial connection which could make it simple to interface with complex projects. This car project is a cool example of the possibilities.
"The OpenStepper Module (OSM) is comprised of a GSM_01 and the OpenStepper circuit board. OSM firmware is based on Mike Thompson’s popular OpenServo project which Jay Ragsdale was kind enough to port to the ATtiny84."

Ahh man, I ported the damn firmware. Oh well. Its a neat little toy, and you should all buy one. Code is hosted over on OpenServo.org CVS.
As a amendment, it uses daisy chained I2C connection, not RS232 or similar.
Cheers, whiny OpenServo maintainer.

HI Ginge,
So it wasn’t ported by Jay Ragsdale?
