A thousand points is not a laser. I don't know what it is. I don't think it's a beam either.
Think disco ball.
If you have never had a chance to go see Brit Floyd, the tribute band, I can not recommend them highly enough, the light show is worth the price of admission and they are excellent .
Your comment made me think of the disco ball and that made me think of a Brit Floyd show I went to. They light one up during the guitar solo for Comfortably Numb and it will blow you out of your seat when you see it live.
Skip to 7:30 in the video if you don't want to watch the whole thing.
