LEGO builder Marco De Bon has created a movie-perfect 1:1 scale recreation of the Ghostbusters trap that looks like it truly could contain a focused non-terminal repeating-phantasm aka a class V full roaming vapor. Marco said he modeled his trap on a mélange of several films in the franchise (there is no single canonical version). The tiny details are what make this build work. For instance, look at the handle made of tires to add a nice ergonomic grip before sliding it across the ballroom floor of The Sedgewick Hotel. The interior of the trap also detaches so you can slide it into your custom made storage facility. Do look directly at this trap.
