An experiment in using the Wii to spray on virtual graffiti, hence the WiiSpray. Nice idea and great exploration of the use of this kind of interaction with the projector.
It’s still an experiment, but may provide an alternative to trains, buses and seats hopefully.
And the techie bit: It uses a Wii but the actually graphics are built using Adobe Flash. Seems flash is becoming a great tool for experimenting with ideas and interfaces.
