Light Graffiti Cans from Shampoo Bottles

These light graffiti cans give the feeling that you're spray painting with light.  Combine these with the free software at http://glowdoodle.com/ or http://mylightpainting.com/ and you've got a virtual 3D graffiti wall.  You can also use these with a long camera exposure in a dark room.

This version is very easy to build and requires few tools.  For building these with real spray paint cans, check out this tutorial:

Thanks for the link! It looks like the "day mode" and "fade on/off" options will be very useful.
