This is a neat little one-chip circuit we originally tuned for use with our "SM1" Stepper motors. We've presently sold out of the motor, but this circuit has proved to be a good unidirectional (1-way) driver for small stepper motors.
MakerBEAM

Ok, besides being a conjunction of two things we really love (Make Magazine & BEAM Robotics), it also is an open-source hardware project that is about little "T-Beams".
This project is using the "KickStarter" model of sponsorship. Ask for pledges for the projects, and if the minimum is met (and it has - yay!), the project will go ahead. Of course, more funding equals better chance of success. In celebration of them making their sponsorship goals, Evil Mad Scientist Laboratories has a Q&A article with them.
We twittered about this a good while back (ok, it was a retweet of a staff member), and like to think we helped them get the attention they deserve with this project. We've pledged our support to the project, because these looks so handy for building small machines. Take a look - it might be of interest to you too!
