You're right, but I think that contest should not last that long and should resolve in very big projects. I think a month (or two) for a small or middle-sized project (I'm speaking of programming) is more than enough (if you really want to get it done). And for such projects, a public voting would be sufficient.

What about programs? Something like getting the fastest fps-rate when doing some special kind of animation?

Yeah, but who would make a game with a gameplay of 8 hours or more for a contest (besides some of the "program of the year"-contests)? I think a contest should focus on smaller things.

For games, everyone should be able to vote.
For programs, you can set up a value for each contest that indicates the winner.
Pixel art is difficult, but like in previous contest, you should focus on small stuff
Movies (if they should really express somethin) should be voted by all people plus a few judges. Then some kind of system could add the results together to receive the winner

there should be judge I think, but we need more than two and add all scores together

I think having the people vote on pixel art contests like we've done in the past has worked really well.  We could do the same for the movies, as they aren't that hard or long for people to judge.  However, I do believe that for the programs, we would need a set of 3-4 judges that would thoroughly test and play all of the games fully in order to give them a fair score.  I don't think that having the average member judging them would be a good idea as this would lead to biased judging as well as un-fair judging from people who only played a portion of the game or played very little of it, and just made up scores for them.

any one else?

well, since I am eager to kick these off-
this issue is decide and as a lack oposition I suppose all the other issues are ressolved to.

I dunno I am not really in charge of this contest, plus atm I doubt I would be able to manage it, maybe we should start polls about game theme?
