About
FriiSpray is a guerilla infra-red graffiti installation developed by the Jam Jar Collective. It uses a custom infra-red spray can, a projector, an IR Webcam, a computer and AIR Graffiti Software. The installation is a back projection on a screen and allows the users to digitally graffiti using the custom made spray can.
Here is a video of AIR Graffiti Wall in action:
How it works.
It works by sending the position (x,y) and on/off signal from a infra-red LED (similar to those found in many TV remotes) mounted in a spray can to the infra-red camera in the front of the IR Webcam.  This signal is then transfered via detection to a computer via AIR Graffiti software to control the mouse pointer.  This in turn controls the paint spot in the AIR Graffiti application.
Uses
The original intention was to recreate a clean form of digital graffiti where the user could virtually spray paint straight on to a window in the centre of town. This was partly inspired by the work of the Graffiti Research Lab [GRL] who have created open source forms of expression such as LASER tagging and the LED throwies. FriiSpray instructions for the 1st infra-red spraycan be found here.
We have since run workshops for various ages and also private party events giving people the chance to try their hand at virtual graffiti themselves.
