> What are the terms of use of this art?
From contest rules:
"All submissions must be original and you agree are public domain on submission"
BTW - I've added a link to Leah Goodreau's gallery for those interested in her doing any work on the mascot or other work -

> Assuming the terms are reasonably open, where can I get the original or high-definition files?
I have added a link to the original PDF on
http://gnoga.com/mascot.html
> BTW - don't forget about T-shirts with this logo. ;-)
If it catches on, I think a good idea.
