Is 300x300 the right resolution? I can't find my wikipedia login to upload it, but I will if I'm the right person to do so. (Am I? I'm a little reluctant to interact with this thing since last time we got accused of conflict-of-interest editing just for answering questions about it.) If someone else should upload it instead, here's the image and my best shot at a "non-free use rationale".

(That's on our
page o' banners and stuff, btw.)
{{Non-free use rationale

| Source = Original design by graphic artist Jonathan M. Chaffin, supplied for Wikipedia by Ben Phillips, CEO of Escape Artists, Inc.
| Portion = This is the "album art" included in every podcast episode, which is incidental to the value of the works since they are all primarily audio presentations.

| Purpose = This is the podcast's logo and also the "album art" included in every podcast episode.
| Replaceability = The logo is copyrighted to Escape Artists, Inc., which grants permission to reproduce it not only to Wikipedia, but any media outlet or web page linking to, referring to, and/or writing about this podcast.
