SPIDER

In 2010, Kollision was commissioned to create an interactive floor installation in Faarup Sommerland. The installation was to be a part of a new attraction, The Fox Hole, based on the idea that after closing time the animals of the surrounding forest invades the theme park. The Fox Hole is staged as an underground world where the visitor meets a variety of fun, challenging and scary obstacles while in search of the fox.

The interactive floor created by Kollision is situated in a dark narrow alley in the Fox Hole. Using projectors we created the illusion of an old, wooden floor projected onto a concrete corridor. When a visitor approaches, spiders emerge from the cracks in between the floorboards, and when the visitor steps into the corridor, hundreds of small and large spiders suddenly appear from underneath the walls and start chasing the visitors brave enough to cross the floor.

The installation is running on a tracking library, developed by Kollision, that analyses a video stream from an IR-camera mounted in the ceiling along with an IR-emitter. In this way a computer placed with a projector above the ceiling calculates the positions of people on the floor and spawns spiders according to the activity on the floor. The spiders behave according to basic flocking behaviour similar to schools of fish and flocks of birds, creating a scary and realistic swarm of spiders.
