hrmm.. not sure if this is a scanner or what then, but it was pretty cool (a bit laser-like) when I was there that night, in the front haha: http://www.youtube.com/watch?v=hpMu8ZRDILo (halfway through shows it from the booth)
if scanners are what creates that then they aren't that bad. i still prefer a bunch of the others though.. like all the moving heads at 2:45 and on of the video!
and really as previously stated by jussed you need a mix of everything.. changing ambient lighting, moving heads, strobes, screens, etc.

Laser/Scanner?
At the beginning of the video that orange light circling around the DJ booth sure looks like a laser, I can kinda tell from the thickness (or lack their of) and sharpness to it. Now half way through when its coming straight on to the cam, it looses its laser sharpness and seems to have a thicker beam than it did before (resembling a discharge lamp-scanner/moving head) . Ill beit it, the pattern changed, but the glow of the beam fades into the surrounding darkness which is not what lasers typically do...I dunno you were there, you can usually tell if its a laser or not...but in the same breathe optics from quality moving heads/scanners look laser-like...I'll look around online and see if I find something similar, cause it looks awesome...lovin the orange.

Ya...gotta love them moving heads. I think a good mix is important too...cant just have scanners or strobes or whatever, variety is the wise chioce here. Exlusiveness too...I wanna have something that no other club around has, it helps set me apart from the other guys.
