This is fan art for the new Disney movie, "The Sorcerer's Apprentice".
I found out that the Merlin's Circle that Nicolas Cage's character makes, actually has a meaning to all the symbols.
Once I added the glow in photoshop, I decided it needed something more magical, so I added a little bit of photoshop effects around the edge to show off a little bit of the magic of each symbol.
It only took a couple hours to do, just did it for a little fun.
EDIT (9/3/2010): The time symbol is actually a circle within a circle, so I fixed it.
