I was thinking about the game and had an idea! Wouldn't it be sweet if you were able to earn a tool that you could use to graffiti on certain surfaces in the game? There could be several different colors that you could get, green, red, blue, etc. Whatever Graffiti anyone had done would disappear after a week. I know that it would be an extremely complicated and time consuming project to code, but it would be really cool if it were a feature.
