Currently in a rut with this "Architecture of Memory" development. I came across David' Pearson's New Organic Architecture: The Breaking Wave which appears relatively offbeat, but could be the kind of inspiration this project needs. Let's see what these organic architect's have to say about sensory perception and the marriage of art and architecture.

ORGANIC (adjective):
1a) of food; grown or made without the use of artificial chemicals
1b) not using artificial chemicals
2) of, relating to, or obtained from living things
3a) forming an integral element of a whole
3b) having systematic coordination of parts
[First known use 1517]

"What is synesthesia? It is not, van Campen concludes, an audiovisual performance, a literary technique, an artistic trend, or a metaphor. It is, perhaps, our hidden sense—a way to think visually: a key to our own sensitivity." Although I was not entirely fond of van Campen's writing, I thought he brought up some interesting, valid points, in particular metaphor. I could see why people without the condition would use metaphor to relate and describe the condition, and I agree with van Campen for concluding that synesthesia is not this, metaphor. His approach determines what synesthesia is not, to prove his theory of 'the hidden sense.' Regardless, the book is a good read, especially for the study on the topic; its nice to see different view points and understandings from non-synesthetes and Richard Cytowic to help develop my own thoughts on the subject.

METAPHOR (noun):
1) a word or phrase for one thing that is used to refer to another thing in order to show or suggest that they are similar
2) an object, activity, or idea that is used as a symbol of something else
[ORIGIN: Middle English methaphor, from Middle French or Latin; Middle French metaphore, from Latin metaphora, from Greek, from metapherein to transfer, from meta- + phereinto bear, first known use in 15th century]
