I was bored with portals so I decided to use my Java skills and build a working Star Trek Style Transporter.

It uses 2 repeaters to set up to 8 destinations by changing the positions of one or both repeaters.

Flipping the lever "energizes" the transport process.
You'll have eight seconds to get to the pad before transport occurs.
The lighting goes from red to white on activation and their are "transport" effects using portal blocks.

You can try out the result on meledosia.com on the Skyland map.
