[Release] Quantum
[This map is not made by me, but I got the authors permission as he apparently can't post it here]
Found this over on another site and liked it, it doesn't look like it was posted here. I asked Omnicoder and he told me it was fine if I wanted to post it here.
Download
(Download is from a website called The cake is a pie because I was told me posting a link to myApertureLabs here might not be well received)
Once again I DID NOT MAKE THIS!
edit: oh and does anyone know why he didn't post it here
Well, there are more maps which are posted somewhere else and not here. I guess it's because this site is apparently tearing apart.
Anyway, I have played this map a long time ago and liked it. The balanced difficulty got me 
(percentage calculation sphere self-test failed!)
108.1% done, -8.1% remaining...
Released here!
All maps for Portal (1/2) worth playing are mirrored here.
Omnicoder did not post his map here because he is banned. But thankyou for posting this. I might play it in a few days.
Why is a big portal mapper like Omnicoder banned? And why is this site tearing apart?
I like the map by the way.
I like the map by the way.
Please look at the date of the last post. That was a year ago, when I think the database broke.
Pretty sure Omni's no longer banned, I remember msleeper saying all outstanding bans were killed when the site was updated to its current version.

Your download link doesn't work? TCIAP is down for a long time now. 
Yeah, TK took it down a few months ago because it really hadn't taken off. Here's the download link over at mAL though.
