Jose Luis Pajares's List: pixels in the wild

The wall is painted with glow in the dark paint and the roller (wich actually doesn't roll) has light in it.
Here we can see it in action too:

Other applications of UV light drawing (with a pen instead of a roller): http://www.youtube.com/watch?v=MIxhmKjIEGg

Random interaction gave another turn to its Pixel Roller applying a regular printer to the roller instead of UV light.

Here you can see another version of this installation:

An extension of led-throwies to disseminate light drawings where street-sweepers can't catch them.

The very well known LASER TAG from GRL, the fastest way to create the biggest graffity in the world, althought very temporary too.

Before I saw this for first time, I was dreaming with this kind of x-ray torch interaction some time ago. While here Chris used a torch and a standard external projector indoors, the pico-projectors that start to become available in the market, suggest that the capabilities of this kind of interaction can be explored further.

I like the way it allows to play and augment the physical drawing with digital versions of it, without having to go out of the surface of your table.
