My MkII proton pack for Halloween 2010.
I made a Ghostbusters costume a few years ago and it was great fun to ware, but knew I could do better so this is the MkII. There is a lot more I would like to add (maybe next year), but it will do for now. The costume got me stopped by the police (so they could take photos) and drew a crowd on the train.
MkII now with lights, sound and smoke.
