Where is the Pinwall

[Deny]

Hey you

I love the game so far, even though my brain hurts from the puzzles.

I got collect some stuff, and the Game tells me either to open the inventory at an terminal or look at the pinnwall. (don´t know if that is the corect word, play it in German)
But wehre is the pinnwall? I just can´t find it......
