So I'm to believe that if I were to snort a couple of Pixie Sticks, then blow my nose on a canvas, frame it, get oohs and ahhs from an audience...

...art is art no matter how it came to be.

Originality scores points with me, but it isn't everything.
Some think the complete opposite.
That's life.
Some people use Photoshop, I prefer PSP.
Some feel a work is incomplete without postwork, I like my work "as rendered".
What's the difference?
Preference.
What's important?
The end product.
Art.
It's more than just a picture.
