Drawing with other people in the world

This “artsy-fartsy” website has a pretty cool underlying idea behind the premise of the website. The website is simple- you draw a line on a page, and try to fit the theme of the artwork. Each user can contribute a small amount of line per visit, then they are given the opportunity to vote on the opacity of lines submitted by other users. By voting, users moderate the input of other users, judging the quality of each line. The darkness of each line is the average of all its previous votes.
