How are you defining it?
In my view, if it looks like a 5 year old did it then it's crap.
So, how about this?
This is a painting btw...
Is this just crap?
I don't consider this to be modern art. I don't care if it was created this morning.
I'd like it if my 3 year old did it, and I'd post it to the refrigerator to humor him, but it would be down by Sunday.
