The first year anniversary is celebrated with clocks and paper. At least, that's what they say.
If you go the traditional route, you could make him a clock with images of his fav MMORPG as the faceplate. Even if you can't print out the images, you could probably pick up a gaming mag with enough pictures. Or, since he's a programmer, the binary clock from thinkgeek.
Otherwise, how about a computer screen cleaner
done up as his fave MMORPG critter
, or as his kitten. Or, the ever so ubiquitous ipod/laptop/PDA cosy.
