Portal Device Inverter: The Unused Technology

Deep in the Aperture Science labs, there still are untouched chambers with technology never seen before. It's up to you to uncover it.

NOTE: For the sake of gameplay, don't try breaking the new game element by jumping ot crouching through it.
_____________________
My first take at building overgrown and broken chambers. Any suggestions/reports/feedback are appreciated.
The rules of the element are pretty simple: it changes the portal types of yout portal device. This level only introduces the element and how you can solve regular tests with it. I have some ideas for chambers based on the element, they will be out when they're ready. The puzzle of this chamber is not very hard. Enjoy!
