1. Rotate yellow beam to face west
2. Enter blue portal
3. Drag west pillar down so it meets yellow beam
4. Rotate blue beam to face south
5. Enter yellow portal
6. Move yellow beam up and right, then rotate to face east
7. Enter blue portal
8. Enter yellow portal
9. Move south pillar out of the way of the cyan beam, then renter yellow portal
10. Move red beam out of the way
Now you have cyan portal in center. Repeat similar concept to get the northern cyan beam facing east on the pillar that leads out.
