I created this icon for the open source instant messaging app
Pidgin. I hated how its default icon looked in my dock, and I couldn't find another that I liked, so I whipped one up on my own - and I rather like it.

(The screen crop in the bottom left shows how the icon looks on my desktop with
AWN.)
I tried to keep this within
Tango's style guidelines, and for my first attempt, I think I did fairly well in that respect. It's obviously modeled off of AOL Instant Messenger's old "running man" logo - traced in Inkscape - but tweaked a bit, with a purple color palette and another visible arm.
The zip archive includes the SVG file (for your resizing pleasure), and a 128x128 pixel PNG. Let me know if you like it!

i was thinking the same thing.
But what about this: [link] ?
