LED Throwies

A creative way of using LEDs as artistic light source.
LINK for how to make one.

These are works of the Graffiti Research Lab a division of the Eyebeam R&D OpenLab

The basic idea is to light up a LED using a coin battery. If you add a magnet to it, you can throw it to a metallic surface and expect it to stay there. It will look impressive when a group does it, as below:

Looks fun, a good way to decorate the bare boring metallic wall, and a good way to exhaust coin batteries.

Environmental concern: What will happen to Li-ion coin batteries when they are left on the street wall, exposed to weather elements?
