FriiSpray is a guerilla infra-red graffiti installation developed by the Jam Jar Collective. It uses a custom infra-red spray can, a projector, a Nintendo WiiMote, a computer and open source software. The installation is a back projection on a screen or large pane of glass such as a shop front or large window and allows the user to digitally graffiti using the custom made spray can.

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 is free to download and use, the instructions for the 1st infra-red spraycan be found here.

We are currently working on FriiSpray version 2 which has new can technology including a distance sensor and pressure sensitive cap switch. It’s a bit buggy at the moment but getting there. We’ve taken the setup to quite a few places across the UK and tend to have quite a lot of fun doing so. Pop over to the education section to see our work we’ve done with schools and other institutions.

We’ve had loads of requests and suggestions about how we can improve FriiSpray. We’re really excited about all the possibilities. This is the first of more updates to follow that start to implement those features. Version 0.77 now lets you load a background image to spray over. This might be a photo of a wall, a previously saved FriiSpray image or anything you like really. To use this new feature simply press cntrl + o.

There are also some minor changes that should make the software a little bit more efficient, and a fix to a bug that meant it sometimes kept drawing when you didn’t want it to.
