Can one create a fully functional 3x3 portal? (That's 3x3 on the inside, and 5x5 on the outside)
If you're wondering why I would want to do such a thing, it's purely for aesthetic reasons. I have a room with a wall 3 wide built deep within my base and it would be more trouble than it is worth to resize the room. Hence a 3x3 portal would be perfect.

As of snapshot 13w37a, you can now create portals of any size between 2x3 and 21x21. This is a feature in Minecraft 1.7.
As of Minecraft 1.5_01, only 2x3 portals can be created (via Obsidian frames) to provide transport to the nether.
1You can use inventory hackers to give yourself some portal blocks (data value 90) to place down, seeing as it gives you no advantage as such it's not really cheating...
1According to what I know, the 1.7 update allows you to build a portal at any size, but it can't be any smaller than 3x2. So, you can make a Square 3x3 portal, If that's what you're talking about. if you have a 23x23 room, internal space. then you will be able to build the maximum internal space portal, 21x21 internal space
1You can hand-place portal blocks (not the obsidian frame, but the actual purple portal blocks) using MCEdit, which is an external world editor. By hand-placing them, you can make a portal of any shape and size.
