Who's your favourite painter, sculptor or any other visual artist?

Mine used to be H. R. Giger, but since then I've come across many others... now the best of best for me is Kris Kuksi. I kinda dig Gottfried Helnwein too.
Btw my everyday experience from browsing DeviantArt is that there is HUGE number of great (mostly digital) young artists in the world, especially in game industry. Concept artists in particular. Even my personal favourites are too many to count. Go, visual arts!
