Overall, the public is being pretty discriminating-- the highest score I can find is 3.5 out of 5. Standouts so far are Pluto, AOR, California, and Plexis, but voting just started, and it's supposed to go through next Wednesday, so I'd expect things to change between now and then.
If you're bored, head over to MacThemes and pass out a few ratings for the cause. I guess the public rating will count for half of the final score (with judges accounting for another part of the score), so every vote counts. We should see the winners sometime after the 15th.
