Salvador Dali is my all-time favorite.
I've been the the Museum in St. Petersburg numerous times. I love his work so much. It's just so full of many random details yet somehow ties together. It's really hard to really appreciate them from a computer image.

Some of my favorites...


I hope no one's offended by this because it's merely art, but I have to say this is probably my most favorite piece of his.
