I've been walking by this little mosaic for a few years, but thought I'd finally get some pics and share them. It is outside Flux Factory, an art/performance space near my apartment in Queens. Maybe you've seen some other videogame-inspired murals/mosaics around NYC, or in any of a number of cities around the world. Many are related to a project headed by a French graffiti artist called Space Invader. Pac Man ghosts seem rare in his work; Space Invaders aliens are much more common.
See a close up of Inky after the jump.
Here's a link to a pic of the same thing on Space Invader's site.
