This is a very rushed and excited attempt at a description of an idea I just came up with for my degree show!
Keys hung from the ceiling above a tank of water (or liquid substance – jelly could be interesting!)- A nylon string suspends the keys; they are at different levels with a tank beneath them, which represents the brain. The keys unlock memories. Some of the keys are above the water; others are below the water (Could incorporate a mechanism so they move up and down, some slowly some fast, repetition of memories?) The keys are different shapes and sizes, each memory unique. Beside this have the vacuum formed images and other casts?
I’m now going to get on with the D-word, I thought I would just get this idea down; it’s definitely a keeper!
