Really cool and easy 3D printing project to entertain the kids or friends who are easily excited by LASERS!

“Got a family member with a low I.Q.? Print this for them, they’ll have fun for hours!” Lol. It is neat though. I think I’ve seen this on thingiverse somewhere.
Great narration and explanation. I’ve always had a hard time explaining why one would need to learn sin, cos, tan, etc. This demonstrates it nicely.
This is pretty cool.
Definitely going to make this and do some guerrilla light graffiti around town.
