I've just returned from Ad Astra, Toronto's primary literary convention for science fiction and fantasy, and while it wasn't Worldcon it was stellar in its own right. As you might expect there was no shortage of costumed attendees, and given the course of recent trends, it should not come as a surprise that the steampunk aesthetic was common. Take, for example, this natty gentleman, who with some patience explained to me that he was a man of mad science and steam. I especially liked his mechanical spider pet. Or whatever it is.
