Aperture Dèjá Vu
What is Aperture D?j? Vu?
It's a non-linear map which have many paths to take and reach the end. The point is, that you play a map one time and you are happy. Then you have a little break in Portal, because there aren't any new released maps for some time. But the answer is here: play the Deja-Vu again, but choose a different path with different puzzles. You can choose freely the way that is going to lead you to the end.
Features so far?

Unlike other mod developers I wish you the best of luck. Looks awesome, but I beg to differ that it has the same portal design as Valves.
Again, I can't wait. 
The more you give, the less appreciated it will be received.
Skinnycap, just make sure that the new voices are GOOD and not MIND WRENCHINGLY HORRIBLE.
OH BOY!
just downloaded the demo and played it...
pretty good... it is a bit tiring going through all the possibilites, and there r only four... it would be tedious to do all of the ones in the proper mod id imagine...
one thing: emancipation grills into and out of each chamber doesnt actually do anything... it doesnt get rid of portals in the room u were just in...
other than that, the chambers r good, only one irritated me... :p

I know that the DEMO map is kinda bad and that voice we used there is not that one we gonna use in the real one etc..
But the real one is much better, i think i gonna release it next month:D i hope.
I have make a new skin of the hair of Chell but it's kinda bugged.
watch here ---> http://www.moddb.com/mods/aperture-dj-vu/images/new-face
I don't know where the gray hair comming from, is it possible to delete them or something?
I really don't know how, never did re-skinning much. Perhaps its were you can't see it in the .vtf file. .
Anyway, Keep up the good work. 
The more you give, the less appreciated it will be received.
Yeah, I just signed up for 2 reasons:
1. I like the site.
2. I wanted to show off a little because of my beta-tester status for this mod. No really, look on the ModDB page.
Anyway, I really can't wait for the mod. But my question over at ModDB was never really awsered. But it's a secret to the public (at its topic), so I think I'll email.
