![Some fine Ghostbusters cosplay. By Flickr user rparle.](https://web.archive.org/web/20071111012548im_/http://www.blogsmithmedia.com/www.diylife.com/media/2007/11/ghostbusters.jpg)
It's been over a week since Halloween. For days, you've been nagging your roommate to take down that ghost decoration they put up in the corner of the living room, near the ceiling. The trouble is, said roommate (who is usually pretty good about washing the dishes and not using all the toilet paper without buying more) claims not to have put up a ghost decoration anywhere in the house.
Meanwhile, the ghost stares at you balefully, waves its arms around, attempts to make spooky noises, leaves ectoplasm stains on the walls, and is starting to gather dust. You think you may have a bit of a problem on your hands: you're not afraid, you're annoyed. So, who you gonna call? There aren't many actual exorcists in the phone book, let alone Dr. Peter Venkman. (Does he even count as an "actual exorcist"? I mean, have you seen the man work?)
My prescription: get a copy of Ghostbusters and run it incessantly on your DVD player this weekend. At the same time, visit the Ghostbusters Prop Archive, a site dedicated to building all sorts of replica props from the film. Make a point of lingering on the pages for Proton Packs and Ghost Traps: print out a few plans, make some notes, and, most importantly, let your uninvited house-guest see you doing it. Periodically make calculating glances in his direction. Munch on marshmallows.
If your ghost is a reasonably bright ghost, he'll put two and two together and head for someone else's apartment. He doesn't have to know that you're not figuring out how to build real ghost traps, right?
If you just want to make some costumes and props for Ghostbusters cosplay or fan films, the GPA would probably work for that, too, I guess... because I'm joking about the exorcism idea. The site has all the detailed information, screen grabs, and building suggestions you could possibly need to make your project a success. There's even a small shop full of elements that may be difficult to find: knobs for the goggles, belts for the uniforms, etc. Get busting!
