Also, I've heard of people talking apart their phone and other LCD screens to get all kinds of cool optics. Maybe, if you truly don't need or use or want the cell phone anymore, you could do that.
im gonna stick with the basics
Gonna just make a laser field lol
Itll be cool though, ill buy plastic mirrors, cut them to small pieces and place em around my room
Then ill have the laser bounce across my room and the last mirror will lead the laser to hit a light catching prism i got(it makes little dots and diamonds)
