That's kinda neat with the Post-It notes, but the monsters themselves are meh. It would have been interesting if he/she took a retro game and made a scene that wrapped around the room and "looped" -- meaning the two ends of the scenes were connected seemlessly. But hey, I'm no 8-bit artist so maybe it's a bad idea.
The reason people get attracted to the I Am 8-bit stuff is because it taps into the nostalgia of retro and classic gaming. This guy/girl, while he/she created pixelated monsters, doesn't create anything recognizable (to me at least) and, thus, isn't as effective as his/her American counterparts. It's nice to see someone trying to get the idea of having a German 8-bit art exhibit out there, though. Maybe this will attract some additional talent and something serious can get rolling.
