Sony released a 30th Anniversary Blu-Ray Edition for Ghostbusters last week, and it features a statue of Slimer and the Ghostbusters logo. I can’t tell if that Slimer statue is dirty, or if I have a dirty mind. Anyways, I would’ve just made a snap case from the Ghostbusters sign:
At almost 1.5″ thick, there is plenty of room in this case for additional discs, booklets, and even batteries and LED lights for a light-up feature. I’d also include mounts on the spine so you can hang it on the wall like a clock, allowing this case to function like the actual Ghostbusters sign.
