We've discussed having a photo.se style continuous contest to provide a "featured render" for display on the main site before, but now that we are graduating it's time to see about making this happen.
Basically everyone who wants to enter would post their render on a massive meta thread, then every so often the highest voted entry would be displayed on the main site. Once it's had it's turn, the entry would go into a "hall of fame" meta post, making way for new renders to become the highest voted. The idea is to have a very relaxed "contest" that anyone can participate in without having to worry about a boatload of rules and restrictions. As a bonus, we get fresh pretty artwork on the front of the site on a regular basis :)
How can we work this idea into the design of the site? What kind of special considerations can we have implemented to streamline the operation of this contest? E.g. automated ways to feature and move posts to a hall of fame on a fixed interval (perhaps with a way to adjust the interval, so we can speed up the turnover a little once more people participate).
