Hi. Welcome to the incredibly amazing Pie Menu window manager page! Unsurprisingly, this window manager has been extended to use pie menus. In a past life, it used to be tvtwm.
We've got a mailing list. You can download the software. You can even see a screen shot of a pie menu popped up, and a shaped pie menu. No, you haven't gone colorblind -- I just haven't had time to customize my colors yet.
