Bring in stuff about four dimensional beings who can pass
through solid matter, and explain how they do it,
scientifically. What about the world of clear?* Where the
refractions of light were the only way to distinguish one thing
from another?* Where you can see through clear to the end of the
Universe, and beyond? Or there is the world of where you are
sitting on the garage roof, sliding down, and entering a world
of pipes, or another time where you go on a mission through the
underworld, with the purple rock bridges and flourescent purple
lava.
