There's the "Cheater's Cubist Movement":
And the more homespun "Folk Art":
"Shock Art" tends to live up to its name:
While "Fluxus" - so named because the sense of proportion is kept in a constant state of flux - is my personal favorite:
And lastly, there's the genre-spanning "Lowbrow Dali Deconstructivism":
Thanks to Renee, Becca S., Kim S., Allie L., Diana D., Katie H., & Bridget F. for today's movements.
Note: No, I didn't make those art terms up; you can read the [ahem] "real" definitions here. And my apologies to artists everywhere. ;)
