@Petutski - Yup, that is an accurate description, at least the tedious part is. Not sure about the brilliant. I think there are some good things in there but way too many options that aren't clearly defined. It was my first laser map and I way over-reached. If you get to Laser Madness 2, you'll find the same problems with the last room(the first two rooms are pretty cool, though). My apologies ahead of time.

Well, the possible combinations of a boatload of cubes and lasers has be in the 100's, if not 1000's, making this map extremely tedious along with being brilliant. Thanks for the walk-through!

Ok, I've made a change that effects the beginning of the 2nd room to make it more consistent with the rest of the puzzle. I've also added the two hints above the second of which might possibly be relevant to how you got stuck.

Ah yes, the drop a cube on the other and tumble it upwards. Some of us know that one. So this puzzle is definitely not for noobs. I got the big shit-load of reflector cubes, but I can't seem to find where the trigger is for the laser pointing up. it's got an "O" or "circle" for signage, but I can't seem to find the trigger to match it.
