Science is more important, but art is still absolutely important. Science furthers our understanding of our world and our universe, whereas art furthers our understanding of ourselves, and each other.
Artists probably aren't going to discover the cure for cancer or solve the energy crisis, but scientists aren't the first in line fostering social evolution, and they probably aren't writing the songs that help us all get laid.
Seriously though, there's a surprising amount of contempt for art in this thread. Isn't this the forum of an online periodical dealing mostly in coverage of an entertainment medium? A medium that combines the efforts of science (computer engineering) and art (design, writing, music, etc)? A relatively young medium that is still struggling with its identity and whether or not it can be considered a viable form for artistic expression? I wasn't expecting to find any "art is stupid, and anyone who prefers it to science is an idiot" around these parts.
Don't forget, science is important, but it's also generally pretty complicated. Art is much more accessible.
Personally, I like it best when science and art work together and give us things like... well, video games.
