Here is a pair of World of Warcraft symbols I screenprinted for my sister and her husband, the mage n' lock as a wedding present. Getting the symbols to look good is actually a little bit tough because I grab the images off of a google image search and they're usually pretty pixellated and not that contrast-y or clear.
Each print is something like ten inches in diameter and nicely framed. They put these up in their computer room / WoW lair, along with this one. I think they add a nice pop art flavour to the room!
