Speaking of ninja tricks...
Right now I know:
Cube throw: (throwing a cube to hit a button)
Cube jump: (cube flying through 2 vertical portals and then jump onto the cube to reach platform)
Vertical portal jump:

Portal Bumping.
I can't seem to get that working
Also portal bumping works with glass frame props, so look for a map with a frame for glass, and it's in between portable surfaces. I found one in the collaboration course.
I think Valve got lazy after mapping for the SP campaign.
I found misaligned textures, they forgot to add portal bumpers, the outside of the walls have no nodraw textures, just bts textures (why it's laggy), and some of them are sloppily done.

Many people get that working in the catwalk stairs in the elevator, they call it wall strafing, works with some surfaces too.

I noticed some of those things as well, however about the nodraw textures: I thought that textures that only touched the void didn't need to be nodraw?
Anyways about the portal bumping: here's a great vid (portal one, but still works in 2:)

Gooood idea
The wall strafing makes you go a little faster, but could be used as a map element?
Also there's this glitch with the funnels, I (use it for the challenge maps) hold crouch when at the end of the funnel, then you fly, stop holding crouch when you want to fall.
Aerial faith plate + any cube = I fling where I please (needs practice!)
