Well, it's not quite a *logo* per se, and it's inspired loosely by jptxs' above, but here's my idea (maybe this is just a banner ad idea?)

I'm no graphic artist. It's trop facile to knock something off in GIMP, and I lack the skills to make it byooteeful. Plus, I saved it as a gif and I'm too lazy to pngify it.

Perl Monks logo ?
