Like microscopic. Literally!
Experimental artist Kotaro Tanaka has created this playable Pac-Man that requires players to use a microscope. The feed from an original Pac-Man arcade board is run through an XRGB-3 upscan converter and projected on a small mirror and seen through the scope. All of this is housed in a lab work bench.
It creates the sensation that Pac-Man and the Ghosts are like bacteria as they move through the maze. (Not to be confused with this, however.)
This is part of a Pac-Man exhibition in Tokyo's Art Chiyoda, which is a school that has been turned into an art space. Exhibition runs until next Monday.
