I had something happen at a weekend church camp when I was 11 or
   12.* Everything was quiet and I was just watching a fire in the
   fireplace or something at this retreat center with other kids
   from our church. Anyway, I wondered, "What would everything be
   like if there was no color - just refractions of light and
   density of matter?" In my mind, suddenly, I could see through my
   feet, the earth, all the way to the ends of the Universe.* It
   was superimposed upon everything around me.* It didn't really
   seem to have a color; it was like crystalline and there was no
   limit to how far I could see. I didn't even need to zoom but I
   could.* I could look at just "be there", while also staying here
   as I looked around. It was pretty neat; there was no sense of
   distance or anything. Long story short, it stuck with me and I
   can recall it anytime.* I have no idea where it came from; just
   a random curiousity, and I guess my brain was capable of
   rendering some kind of representation of what it might be like
   to have a Universe devoid of color, with just refractions +
   different densities.
