Nice work, looks cool. 2 suggestions, please use a text editor that understands unix line endings! (in vi, i'm getting ^M after each line which means it was saved in windows format). Plus, replacing "#!/usr/bin/python" with "#!/usr/bin/env python2.5" lets you start the program quicker if you hav python-launcher installed. Also +1 with lcuk but all you need to do is remove the "d" rather than commenting the lines.
