Looking for a map where you have to think

Hello there :)

I'm looking for a map that has been posted in the map forums a long time ago, but I can't find it anymore.
These are all the memories I have, maybe someone recognizes this map:

- It's not an official map with the kz_ tag asfaik.
- It's an artificial architecture where you start inside the building and at a later time have to continue outside
- The map has a yellow filter, everything is kinda yellow and olive green (just like rockblock)
- The map looks a bit like a building that's under construction or something
- You start off in a cube with lose stone blocks and you have to find your way up there (it's pretty high). You can only crouch/jump your way up
- It's a hard map with a lot of bhop parts
- I remember someone said the map was very good and has alot of jump "where you have to think"
- The keywords "vanille" and/or "sky" MIGHT be in the map name

Does anybody have an idea?

Thanks in advance

kz_mathland is a map where you have to think, nice map

BUT

you're talking about qsk_iteratio I guess
all of qui's maps are really damn good

is the map a building like a box overview or does it has mountains and those other stuff?

I knew it was iteratio lol
You have to think about where you'll jump next :)
