    It's just caused by the camera. Would be an awesome effect, if only we could slow light down a little bit!

    camera can not handle it, i have she same when i make video's at a special scan speed.
    i use a sony cybershot Exmore R, but still have this FX

    i not like it, becourse when a beam is not a straight line, it is allways fake or bad camera work.
    light beams are allways straigth

    It's the effect of the rolling shutter.

    I too love this effect but unfortunately light travels at 299,792,458 m / s.

    Which all in means its impossible to turn the laser off before the light has gone the full length out over the audience. To turn it off to give varying lengths of beam would require electronics, never mind modulation, far beyond anything available to day.

    ^^^ What White-Light said ^^^

    I get this with stills using fast exposure also, and it can look quite spectacular as in the photo I took from my equipment.

    This sums it up pretty nicely.

    This especially happens when the frame rate of the camera is close to the frame rate of the projector.

    i have a black hole (the desktop edition, if you have a desk that's big enough) and i use it to curve light beams.
    particularly interesting when i use it on top of scan through effects
