I cosplayed as PM from Homestuck for Anime Boston '11 this past weekend! Everyone was so cool, and the Homestuck photoshoot? HUGE. Hopy shit! We got kicked out of not one, but two separate locations by security, because over 50 cool bros in one place are considered a fire hazard.
I took some dumb artsy photos in my back yard when I got back from the con on Saturday. PM in a wet, New England environment? It was the best I could do! If only I'd had a handy desert nearby. But alas.
