Speculation with portals
Anyone ever seen Monsters, Inc or the animated short Presto? Both made by Pixar, both using the concept of portals, both freaking hilarious. You can see Presto on Youtube; since I'm not sure if it's there legally, I'm not supplying a link. Searching for "Pixar Presto" should do the trick.
I saw both of those too. They are hilarious. I think Presto is on the beginning of WALL-E isn't it?
So instead of portal through portal, we should ask about hat through hat?
At the portal passing over you, I assumed you would, but I'm not really sure why. It just seems like you would. Which would be extremely painful, since your head would start moving at the speed of the portal before the rest of you.
Ouch.

Yeah that pretty much makes me say no. Because it makes no sense that something going through a person should make HIM speed up.
Well, I did a bit more thinking about it. It really depends. I'm sure it could be coded so that it does or doesn't.
If it did, the reasoning would be that the portals don't care if they're moving, it's what's moving through them. If they didn't, it would take into consideration the speed of the portal and such.
If it DID, portals on fast moving pistons could used to launch yourself to quite a height, with minimal elevation. 
That'd be cool.
I think that you would gain as much speed as the portal comming at you, if the exit portal is not moving.
If you'd hit a brick wall at 100 mph or if that brick wall was comming at you at 100 mph, the effect would be the same. You'd get squish with the same velocity in both situation.
In the case that the exit portal would be moving, i guess it could increase, decrease or change your trajectory, depending of the dirrection it is moving. This is mind bugling...
Ouch.
But actually you wouldn't notice any pain, because no part of your body would be moving relatively to another. Busted.
Good point.
My neck hurt like hell... maybe flinging my head could be a good therapy 
On another note, if you place a portal on a wall and a camera is there, it falls off right? But if portal are 2-dimensional, where do you draw the line as to what falls off?The paint on the wall?The dirt/dust?
It would in real life.
