Eldritch Hourglass

Prop work done for a class. In a fictional game called ''The Shunned House'' the player wanders around a house trying to 'cure' it of its paranormal activity. To do so, he must travel between the world he knows and the unseen one. Once they discover the Eldritch Hourglass, the rotation of the mechanism allows them to maneuver this unseen world and interact with it until the time runs out.
