I set out to make a complete set of wheels for Themes.  I figured "How many could there possibly be?  Sci-Fi, Pool, Bowling, Gambling...  What... Maybe a dozen?"  WOW was I wrong.  This set contains over 160 wheel images for every Theme I've encountered so far.  From Action Movie to Zombies, it's in here.  And I figured I'd like to give more back to this community.

That said, I'm sure I'll find more and I'll definitely add them.  Meanwhile, if you find anything missing or find any mistakes, let me know!
