I'm about to buy new glasses, and I'm pretty unhappy that is costs upwards of $million in order to get some place to grind some lenses for me. Let's grind some lenses and mirrors for a telescope as a secret, personal revenge!
Laser beams! I don't know what the story is with them, except that LASER means Light Amplification by Stimulated Emission of Radiation, and if we can figure out how to stimulate the emission of radiation we can make some. We can then take pictures of them to serve as backdrops to 1980's school portraits.
Fiber optic cable! It's flexible! Really, there is a ton of stuff in the category of art-able light equipment, and we'll try to track down all of it.
SMOKE AND MIRRORS!
After you take this class you'll be able to impress studs and ladies at parties with your intricate knowledge of the hows and whys of the cover to Dark Side of the Moon. It is worth it.
(Also, I just found this which teaches you how to make a pretty wicked chandelier. I'll just leave this here for later.)
