i love the concept

Aptly named!! Awesome mechanism, puzzle and design. Small, looks impossible, is possible, easy in hindsight. Marks of a great chamber.

impressive very nice let's see paul allen's test chamber

简单又有趣的图！！

Elaborate Scheme

Wow! Moogoo, very clever level. What's more you made ME feel smart. Not an easy task, my friend. Thanks!

unique map!

Really cool idea! Thanks!

l like your map.

x3 fun

Genius

Clever use of the beams.

That was an elegant chamber, nice work

great use of the beams, nice job :o)

Nice test chamber, thanks!

you can use the fly glitch witht the two tractor beams to fly over the gap and go straight to the exit

Very clever!!

Nice fun map.... now that it works!

Fun

Good idea but so much walking for no reason.

I've reuploaded the map -- hopefully this will resolve the download issue that some users were experiencing.

Thanks to Petutski for identifying the issue and the solution!

"An error occured while downloading this map!"
Mevious and Zogor experienced this before. The problem relates to some maps released in 2012. Reuploading fixed the issue.

There is always an error when I try to download this map :/

It won't load the map for me, always getting an error.

Cool idea with the boxes. Reminds me of two pistons

Very cool!
In electronics such device is call multivibrator.
Liked very much.

Would have liked noit running so far.

Very neat! There's a couple of ideas from this that could inspire more maps - toggling between states and the mechanical, repetitive motion.

That was an awesome idea.

Awesome puzzle. Very funny. Thanks.
I recorded my gameplay (valve DEM file format): Download [dl.dropboxusercontent.com]. Comments inside video.

Turrets highly explosive. Handle with care

What an incredibly clever solution! Well done man.

New ideas are always welcome.

That was FUN!!
If you have time try my new map. http://steamcommunity.com/sharedfiles/filedetails/?id=177646882

Funky and out of the box. I like it. A few points, however: First, if you jump to the platforms before you get them moving up and down you're trapped and you have to kill yourself. Second, what is the proper way to get the cube inside the room with the funnel generator? I just threw it above the fizzler but maybe that's wrong? Third, what's the proper way to get out of that room? I jumped to put the funnel on the outside side and then re-adjusted the funnel exit en route.

Innovative.

Pretty clever idea on the final solution!

Thumbs up because there was some different and new, the idea of the lifts alternating like that. Good to see something fresh.

this is so awesome...
great job!

Very Nice I know how it works: Ex. 1 Activated by cube droping on another button in a secret room Ex 2 polarity Switched

Very nice idea!

I was expecting a timing puzzle but I was positively surprised by this little trick that you had up your sleeve, made me smile really. The two puzzles however weren't all that difficult and could have some challenge in them, clearly your mind must've been more in showing off that mechanic rather than creating problems for the more experience players of Portal. Still, a very well thought out thing you had there, beautiful!

How did you make the pressing of the button a single time, change the direction of the tractor beams, even when the cube is pulled from the button? Did that require Hammer?

That was cool, I enjoyed it a lot.Thanks.

It was fun, I enjoyed it.

Very nice map!

Nice one.
One little thing: At the beginning you can simply place a portal next to the cube dropper by jumping up, bypassing the powerjump over the fence alltogether. I guess that isn't the prefered way to do it.

I have tried making a map, where doors open randomly. I tried building a box full of buttons, where the balls bounced around and would land on pads. While the balls bounced around, like in a lottery container, they didn't sit long enough to active a button. Any ideas about how to create randomness in a map?

Pretty Clever.

Great! Thanks.

Very well thought out map. Well done.
