[aclug-L] Put that laser pointing device to use

[David Carmichael <dec2955@xxxxxxxxxx>]

The Idea:

Inexpensive, yet surprisingly powerful laser pointing devices have become
ubiquitous in America.  Millions of people own such a device.  Laser light
stays coherent over vast distances, the beams spreading very little.  In
theory, even a single laser pointer could reach the Moon.  The original idea
behind Paint the Moon was to organize millions of people in North America to
shine their laser pointers on one area of the Moon at one time, in an
artistic experiment to see if we can create a temporary visible field of
color on our nearest celestial neighbor.
