Quixote Powered logos
I put together some logos that could be used on sites running Quixote. The main idea is to have a fairly neutral background that would blend well into most pages, the words "Powered by Quixote of course, and some Quixotic attribute. I chose to draw a windmill that hopefully reflects the honorable attempt at "yet another python web framework" with a little "Monty Pythonic twist" (5 blades 
).
First version Largest logo.
Second version Largest logo.
Third version of this logo set, based on suggestions by A. Kuchling and J. Dukarm.
Largest logo.
Medium logo.
Small logo.
Yet Smaller logo.
Here is a more traditional 4-blade windmill logo, too: Largest logo.

Alternative windmill
A five bladed windmill is a little strange looking. I've drawn a (IMHO) cool looking windmill based on a photo of a real windmill: Alternate windmill
It's too busy work a small resolutions but it could be simplified. I've made a basic logo using it:
quixote50
quixote80
quixote150
Yet another choice
