Portal's Edge - Mirror's Edge E3 Demo recreated in Portal

I saw the E3 demo level for Mirror's Edge and I was blown away by it. I thought it would be a fun idea to try and recreate the level in Hammer using the Portal configuration.

I got about halfway finished with it and posted a video of it on Youtube:



Much to my surprise it got featured on Kotaku, which then helped it spread to other games websites. A week after posting the video it had about 200 views. As soon as Kotaku picked it up, it went up by 60,000 views in a couple of days.

This new-found popularity spurred me to complete the first section of the map, which I duly did and posted another video to Youtube:



This one's not as popular, but still good to have it there. The video says stage 1/3 which is wrong, there will only be two stages.
