Steampunk in Oz

I went to see "Wicked!" in SF with hrf, scotica, and duchessletitia this evening. I knew nothing about the play beyond the very basics, and I was very pleased with how it went. I won't give anything away because of spoilers, but it was very clever. The costuming and sets had a very steampunk flavor, with actual gears appearing here and there. I recommend seeing it for those of you who haven't made it yet.
