i love this picture
it's a 3D representation of the E8 Universe (which is 4D, so I'm not quite sure how that works), but look at the shadow!
From a physics stand point, which is better, surfing or snow boarding?
Ha! There's more going on while surfing, with water and wind rushing all around you -- it's about chaos and taking chances. Snowboarding lets you draw a cleaner line -- it's more geometric and deterministic. The difference between these two is a lot like the difference between particle physics, with it's many quantum particles careening off one another, and Einstein's theory of gravity, the smooth geometry of curved spacetime. I think, for completeness, you need both.
