I'll add my newbie advice concerning show creation -
If you're doing beam shows, keep the images fairly simple.
Images that look good projected on a screen (abstracts, etc.) frequently don't look that great when viewed as overhead beams.
Well-timed, frequently changing and moving basic shapes can make for some VERY effective beam shows!!
With the right amount of smoke and proper lighting conditions, simple shapes, with various shades and colors, look great!!
