When I moved to a new student
apartment, the walls were
as white as paper. I decided to
construct a Mario wall in the hallway.
First I measured the size of
the wall. Then I designed a 'land' on paper,
which would be model for the real wall.
The tiles are taken from the first Mario
World cartridge for the Nintendo Entertainment
System, which I own in my game
collection. I edited the tiles in Photoshop
and printed them on A3 sized paper. All
the tiles are fixed to the wall using ordinary
The resulting Mario wall cheers me up every day. Visitors are also impressed.
