I'd like to see an attempt by the subject to work with an artist to draw what they experienced. I believe what we're seeing is external "takes" on what people subjectively think it looked like, not a subject-centric view.

Where the virtual field projects in 3-space. How it moves with head and eye movements, and focal shifts. What apparent pixel resolution it had, not the imputed DPI, the experiental effect of the actual pixelcount in the field.

Did it flicker. Did it rainbow.

Otherwise, Did it promote Nausea. Did it fail to blank when the eyelid was shut. Did it shut off, when wanted to be on.
