@joshmillard I think it's the orange against the red, in context regularity of the lines, primarily, that makes it satisfying to me. I get a hint of synaesthesia with some visual things. This gives me a sense of the crunch of celery. Doubt that makes any sense but thanks for inducing it!

@howfar Happy to oblige! I've never had any of what I'd identify as synaesthetic experiences myself and find the idea of cross-wired sensory processes fascinating in both neurological and cultural sense.

@joshmillard My guess is it's (for me) something to do with memory function. I used to get very strong déjà vu and a sort of jamais vu like dissociative experience where I couldn't experience the connections between moments in time (while still understanding them conceptually). Synaesthetic impressions have the same quality to them: a sense of "snagging" the same part of my mind. I wonder if dyspraxia (with poor working but excellent long-term memory) makes me more prone to it.

@joshmillard Of course, even if that's the case, the mediation of those neurological phenomena, by culture, into an experience that I articulate to myself is just as interesting a component of the whole thing.
