Here you’ll find a delightfully curious passion project: an assorted collection of 180 lasers and holograms, from the 1970s to the modern era. It’s fascinating seeing how the technology evolved from a giant tube that was water-cooled to a small diode that can be bought for less than the price of a burrito.

The owner, Bob Hess, is an active holographer and passionate about his craft. He has been working with lasers and making holograms since 1980.
