I am curious about light - if the Echo technology is using EM waves of some sort to create the “echo” then light, in terms of wavelength, may be important. I noticed the waking titan website uses green, red, white and grey for the sigil and glyph colors. The Echo-64 website has a lot of red and in curious places, certain words are red and certain boxes and so on… A prism splits visible light - what if there are “prisms” that split other EM waves into different bands?
Also - to widely speculate - the brain processes color very differently sometimes (look at things like color blindness, Synesthesia and so on.)
Hmm, I wonder if in addition to numbers and such, we should be tracking colors more?
