Light puzzles (black out any spoilers please!)

I was just wondering if anyone solved the 4th one yet? It is driving me nuts ... they are not that easy actually, I really had to think for the 3rd especially so was wondering if anyone has the same problems or is the old brain going slowly ... I am pretty sure this can be done by using the old matrix math but somehow it seems odd for this kind of game to pull out the big guns. *shrug*

BTW I am talking about BW here, not the simple ones in the original game but that monster dodecagon.

I couldn't get passed the fourth one either. Well, not without help I mean.
I found the solution in Gas Powered Games' forums.

In the next room there's a big chest containing some random loot and Mask of the Unknown Comic which is a crappy unique helm.

[EDIT]
Some guy's Blog has a better graphical solution: clux.org

Sorry for spoilering.

Could you black out the spoilers please, or at least link it?! *points to title of the thread* *covers eyes*

And yes the 4th one is just plain ridiculous! I am leaving that for last, yes I am. I think I'll try and work it out on my own, I am quite sure it can be done, I used a system on the first three but the trouble with the fourth is that it is not very clear visually - too big on a too small a space with too many lines.

I made a flash version of the puzzle for people who want to try and solve it without having to play the game and find it etc.

P.S. It doesn't have a reset button 'cause I'm a lazy bum, so you'll have to reload your browser.

That's a cool idea, I might have to pass it around. I am actually curious how good people will be at it, without using any additional props, like math etc. Thanks!
