That's a good explanation, the page was really confusing when you're not familiar with how it's done. Also, there's a clock ticking now, counting time to when the theme is revealed.
It's currently at around 10 hours 40 minutes, which makes me feel some pain for Notch since I'm in his timezone (Stockholm, Sweden).
It's 16:18 in the afternoon here now, so the reveal is at 03:00 in the night. Not my peak hour for programming. :)
There are blog posts with the tallies of previous voting rounds, you could search for them if you really don't want to log in. If plan on participating, however, you're going to need an account anyway so I don't see a reason why you wouldn't. If you just want to see what the theme is going to be, just watch the front page and you'll find out together with the rest of us.
