I recall once, circa 1969, when I was doing some Purple Osleyne(aka Haze) with some friends at the S.U. of N.Y. in my old home town. I went to the bathroom and looked into my eyes. And saw the movement of 2 orbiting electrons and 2 orbiting
protons encircling the pupil as thought it were the nucleus of an atom. The symbol you list 2 in, and 7 down comes the closest of any in your art blotter to what I saw, though not exactly. And though that vision occurred 40 years ago, I still recall it vividly as though it happened only yesterday. I should. It's not something I could ever forget. As Jimmi Hendrix asked: " Are you experienced ? " (after 20 trips I should hope so) There's a scene in the movie 2010, where Dave Bowman reappears inside the 2001 Jupiter space ship, and HAL, the computer askes him:
"Will I dream ? " , and "What's going to happen, Dave ? " Something wonderful.
