Note this show was made just before I actually became a brony!
Yeah I have 4 laser projectors for a while actually.
all RGB, got controllers for them (but recently one more of my favourite controllers) because of this it's now easier for me to create multi projector content.
So coming soon:
a 3 RGB laser projector lasershow

Also 3 projector graphics show (just for fun)
And a 2 projector graphics show!
