An easier but slower version of the camera stack seen below.
Intermediate - Camera Stackpermalink
Uses a cube stacked on top of a camera to skip the main puzzle.

This strat uses precise portals to fling to the end of the chamber. It's a few seconds faster than camera stack, but does require some quick aiming.
The angle for the floor portal is roughly between -108.25 and -109.50.
