Reflections on Refractions

	Oil spills are so pretty.
They float on the surface of a rain soaked ground and create little rainbows on 
the ground.
Not exactly like rainbows:
their spectrum is created not by separating the colours in a sunbeam, but by 
destroying some colours and letting the rest go free;
but the effect is the same.
	How do you destroy colours? With colours, the same colours.
Add the same colours and you get twice the colour, or none, or some obscure, 
mathematical relative, like chords of matching bells.
A matching chord of music is like the rainbow of an oilslick.

Creating music with light, ironic in a way because oil is light: the captured 
light of a hundred million years ago.
Possibly the light came through a rainbow in the first place, separated into 
it's components - the nice, nondestructive way to make a rainbow.
But all the years in the ground has taught it a different method, a ground 
method, not as efficient in some ways, more in others.
And it works on the ground.
Now you can reach the end of the rainbow, it's there on the wet concrete.
