This ain’t my CUFP, but I just saw this on IRC and thought people who enjoy it: Roomba Tilt Control with MacBook & Perl.

This project shows you how to use the built-in tilt sensors of the MacBook to control a Roomba. Since Perl hasn’t been used to program a Roomba yet, it seemed like a fun task to show that it could be done (and pretty easily too).

There's a video clip, and source code is available, too.

Makeshifts last the longest.
