Lego Ruined Nether Portal

This is an original build of mine, designed to be built in conjunction with the "new" nether as can be determined by the builder. The pieces vary, depending on the preference of the builder. For example, the frame could be either cobblestone or blackstone.
Please note that this is not a step by step how-to. It is more of a general explanation of how to build it.

These should be fairly easy to see when the steps are shown, and not all portals are the same.

This one looks a little more realistic to minecraft in my opinion.
