Old PC laser game

Hi

I've found this nice but old puzzle game with lasers,

It's called Aargon Deluxe.
I was playing this game even before i had a real laser.
The first levels are very easy and get more difficult gradually, but beyond some point they're nearly impossible for a human to solve.
Does anyone else know this game?

Third result on Google is a free download... looks pretty cool, but I dont have time to check it out now.
