Snøball is a physical videogame that
uses a modified web-cam to track a infra-red signal from
a electronic "snowball". The ball has a impact
sensor that triggers when the ball hits the wall. The
web-cam is modified so that its very sensitive for infrared
light. A double layer of exposed color film is used to
prevent the camera from detecting visible light.
On impact the projector animates graphical snow-crystals
long before the appearance of Nintendo Wii, the intercation
course at AHO played with warious physical input to gaming.
Snøball was part of
a joint exhibition "Remember Winter". The lack
of snow in Norway as late as november gave a pesimistic
warning of what to expect from global warming.
