Your Strangest Form

[polarissruler]

During classes (don't worry; I'm not going to bore you with details), my teacher mentioned the structure of the Classic tragedy. It caught my interest, so after some research I decided to write in its style. And it came to me that while there are many chat-fics, I don't think I've read a fanfictioin written like a play.

It got me wondering - what is a form you want to try writing in, even though it is not widespread (or spread at all)? I've also tried writing some fairy tale-like stories (a failed experiment that I should go back to sometime). What about you?
