Got Windows 8, Photoshop CS6 has annoying display errors (with GPU utilization). Guess that means it's time for Illustrator until there's a driver update, eeyup.
I've been a little self-conscious about submitting vector source files lately, because they reveal where I've been a lazy vectorist. I'm not always concerned with perfection in technique, so long as I can achieve a desired visual result.
Anyhoo, if you like these guys, stay tuned - I plan on making some wallpapers for various devices.
Also... it's almost season 3, guys!
Edit: download from my domain
for a ZIP with high-res PNG and source file.
