Haven't seen too many, and as Steampunk CAN be used in VSF, I thought I'd ask for people to share.
Actually, the con wasn't awash in Steampunk; even the costumes were few and far between from what I could see.
However, I'll share one bad camera phone image caught in a dark hotel bar.

Hard to make out, but there are propeller blades (ceiling fan) stacked on the side,and brass equipment with strange blue glowing lamps.
If anyone else has better of this 'girl genius', please step up!
