"In the spirt of GRL's and Eyebeam's open source beliefs, we are posting the code and executable
for the Laser Tag application online for you to download, dissect, reuse and hopefully improve. The code is
C++ and compiled in a super old school Codewarrior IDE for windows but it is oepnGL based and written
using openFrameworks which is a cross platform library for writing creative code. So it should be very
straight forward to run in Visual Studio, DevC++ or even xcode on a mac.

In its simplest form the Laser Tag system is a camera and laptop setup, tracking a green laser point across
the face of a building and generating graphics based on the laser's position which then get projected back
onto the building with a high power projector." (http://muonics.net/blog/index.php?postid=15)

Graffiti Research Labs have given a full open source and tutorial for making a similar lazer tagging system. After buying a new bulb for my projector and a lazer pen, I am going to experiment with this idea myself. It would be on a much smaller scale, and would make a really nice interactive environment, if there were several lazer pens for participants to write with. I assume that the software allows the control of colours and saturation etc aswell, so it could make for a really nice project.
