Shoebox Holography

This is just way too cool to pass up. I always wanted to try this when I was in high-school, when a buddy of mine had a helium-neon laser. Now you can do it with cheap laser pointer pens!

Shoebox Holography
A Step-By-Step Guide to Making Holograms Using Inexpensive Semiconductor Diode Lasers
Frank DeFreitas, Alan Rhody, and Steve Michael

Sample excerpt
"There are many laser pointers in the market today, ranging in price from a few dollars to hundreds of dollars. In many instances, with the more expensive models you are paying for the fancy casing or adjustable optics. (There are only a handful of diode laser manufacturers in the world, so many times the expensive pointer and the cheap pointer actually contain the same laser.)...Fortunately, the simplest, most rugged (and often least expensive) laser pointers work best for the experiment described in this book."
