full circle rainbows exist!
"Each rainbow you see is unique to you and centered on your eyes so all rainbows form a circle centered on a point marked by the shadow of your head (called the antisolar point). To see light from the top of a rainbow, you look up at an angle of 42 degrees. To see light from the sides of the arc, you look over 42 degrees. To see light from the bottom of the rainbow, you look down 42 degrees. Of course, if the ground is in the way, you won't see the bottom of the circular bow."

"Oh, a sleeping drunkard
Up in Central Park,
And a lion-hunter
In the jungle dark,
And a Chinese dentist,
And a British queen -
All fit together
In the same machine.
Nice, nice, very nice;
Nice, nice, very nice;
Nice, nice, very nice -
So many different people
In the same device."
(from Cat's Cradle, by Kurt Vonnegut)
