I was staring at the scores earlier and wondered if it would be possible to build a fancy bell-curve graph that would show the worst, average, and best scores, and their general distributions. I must admit to being a bit of a stats nerd and liking such things. I think there are some handy PHP libraries that do such things, IIRC...
If anything, could we just have a little field on the score display that shows the average score across all submissions?
I'll have a look to see if there is something off-the-shelf I can use. A little histogram for the score tables wouldn't be a bad thing...
