This one's for you, LQ and Erudite. Some guy, obviously in full support of his girlfriend's cosplay habit, BUILT her an Aperture Science Handheld Portal Device.
Every year, around late August or so, I tell myself "This year, I'm a-gonna assemble the greatest video game Halloween costume ever...assembled!" That proclamation then evolves into "You know what? Maybe I'll get into cosplay, too! It looks so fun!", but ultimately settles into the dust with a "What time is it? Man, I have work to do."
Best costume I ever made? I was pretty happy with my Mario in 2005 and my Wayne Campbell in... 1998. What about you guys? Best costume ever. Go.
