Haunt Trends: Past and Present

Ever notice how every year there seems to be something a ton of haunts seem to be doing at the same time? Sometimes it was a type of prop, sometimes it was a scene, and sometimes it was an entire theme! I thought it could be fun to devote a thread to such crazes in the haunting community and perhaps even try to pin down a date (or dates) for each one. I'll include some examples to get things started and I hope more people join in.

Flying Crank Ghost
Vortex Tunnel
Shaker Cans

Scenes:
