  • nice but are lasers necessary or can you use something that doesn't damage your retina

  • You don't have to use such high power lasers, it will  be spectacular even at eye-safe levels. Plus the beams are always moving and the power is spilt many many times with so many dots. It may also work with a narrow beam light too, I haven't tried that yet.

  • Grymt!

  • Tackar!
