Every day I check the forums and in the Emulator Releases section all I see is releases of Lua Teleporters/Simple bosses.
I challenge anyone that knows Lua to create something `Unique` and release it. It may be a boss, or a teleporter, but there has to be something special about it.
One bonus of doing this is that you will probably gain a hell of a lot of reputation. Most high-rep'd users look for things that are unique and useful; so get cracking!
I myself will rep anyone that comes up with something that makes me smile.
