The Scream of Ghost
When we go to a dark haunted house in a theme park, it gets more scary when people suddenly scream. It is the same as walking alone in street at midnight or going to bathroom after watching horror movies. The fear of ghosts is sometimes referred to spectrophobia, the term for fear of mirrors and one's own reflections.
I want to reflect this physiological feeling of human through this project. The ghost will be created with Pepper's Ghost and will react to people's scream.
