Art initiative Mobile Project Unit (MPU) is taking arcade game Snake to the streets in its ?Snake the Planet? project. The idea is simple: the team goes out on the town in Sydney, Australia projecting the game on buildings for all to see (and play).
Snake itself has a simple game premis: two snakes enter, one leaves. You can kill your opponent by blocking its path with your snake?s tail (think Tron light-cycles).
But the geekery doesn?t stop at simply projecting a classic title on some urban landscapes?that would be too easy. The team went above and beyond, and built a piece of 3D projection mapping software that they used to translate details in a wall?s architecture, such as doors, windows, and even people, into obstacles. Ultimately it allows for the creation of new, custom levels each time you set up shop on a different street.
The hardware MPU used for this project is fairly standard: a consumer-grade camera, laptop computer, projector, and portable battery to power the entire operation. When setting up in a new area, MPU used the camera to analyse the wall as a high contrast black and white image, which makes it easier to extract individual shapes to use as the obstacles. The image is then translated (via the mapping software) from a 3D image to a 2D interactive level, and projected on the wall. The entire process takes only a few seconds to complete.
The mapping software was built using OpenFrameworks and C++. The team is planning on making its Snake the Planet project worldwide by distributing the code as open source and as a more accessible iPad app, so geeks can indeed start to ?Snake the Planet.?
