Hi, this is Cave Johnson here.

We are designing a new laser lock for our secure facility. We need you to crack the lock to see if its possible. You're the best, so if you cannot crack this code, we certainly know that no one else can.

Good luck, and remember: Failure is always an option. Not a good one, but its an option.

v1.0: Initial release
v1.1: Made area around pedastal button black to prevent breaking the map.
v1.2: Changed some links to antline to make clear what its doing.
v1.3: Changed portability around mechanic to prevent abuse.
v2.0: Added light, changed a few things to make it slightly harder (actual puzzle is still the same), prevented another way to break the map.
v2.1: Changed positioning of lightning for better appeal.

tnx to Toncica for being able to break the map and point it out to me, as well as suggesting a few improvements.

Very good, I like it!
Reminds me of a test from myself: 4 Connections
Had fun with it, thanks for suggesting.

Ah, right. I was worried I'd missed something important ^^

Great to hear Cooper Kid. :) The flap above the buttons is just a visible meganism for the puzzle. Once you complete a certain step, it disables the laser.

LP, that chamber was fantastic! I had a go at it last night and was stuck fast, so had to give up. My mind wandered in a particularly boring lecture today and I suddenly realised what to do. Awesome!

Just one query though, what's the flap above those buttons for? I didn't need to use it :/

It is indeed very interesting as I thought it would be. It's easy at the beginning, but when you think you've got the end, it's just out of reach. I never would've thought of using the lasers this way myself. It kind of reminded me of setting up a SR flipflop; I had a college about that last week XD (though I didn't pay much attention... that man was quite boring to listen to).

I didn't find any room-breaking solution. The timing is too short to actually get to the door without shutting the laser down, in combination with the fizzlers preventing portalling. The first laser cannot be redirected properly (too high). You can't exit without the three cubes. So... nope... didn't find anything but a good test chamber! :D

Very tricky. Took trial and error, mostly error. I got great satisfaction in making it into the exit.
