One of them is the all-woman planet suddenly visited by a spaceship full of men. The classic and great example of this is "When It Changed" by Joanna Russ. I've often toyed with the idea of writing a play based on this concept specifically.
Well, it turns out that the local LGBT theatre is having a play-writing competition. They're looking for lesbian-themed plays on a variety of issues and topics. The deadline is May 15.
Hmm. I'm not too sure I could pull off a play, and I'm not too sure I could do the concept justice (I am a straight boy, after all). But it would be interesting to try.
I'll have to think about this one some more. Maybe it's my third April project...
