The question what happens if you put a portal into itself has become a meme with moderate popularity. Yet, I'm aware of only two examples trying to answer that question. 

One example is a video (Portal through Itself - MinutePhysics). While this is certainly a great video, due to the passive nature of a video one cannot explore these portals by themself.

The other example is Portal Explorer - Optozorax (click on "Load\Ellipse Portal in Portal"). When I released this demo I was aware this program existed in the past, but couldn't find the link, anymore. Thanks to "Twenty-Seven" for providing the link. This new knowledge makes my demo a bit redundant, but at least my demo has two features the program in the link doesn't have (collision detection and one can go through the portals).

Hope someone has some fun with it and let me know if there are other cases of portals in portals that I'm not aware of.

Controls:
Escape, M: open/close menu
Alt+F4: quit application (not in browser)
Mouse: look around
W, A, S, D, Q, E: move camera forward, left, backward, right, down, up
T, F, G, H, R, Y: move red portal
I, J, K, L, U, O: rotate red portal
shift, space: increase movement and rotation speeds

Note: Only the red portal can be moved into the green portal. Trying to move the green portal into the red portal will not work.
