Pixels Placed per Instance

One of the things that made participating in this fun was that there was very little vandalism. When you started some new project, as long as you got a good outline up to make it clear to others something was happening, you could go to bed and wake up with the project right where you left it.

There was some vandalism, but not very much. A single person could put together their own art so long as they kept it small and manageable. On r/place you needed a team to fight the vandals or you had no hope.

What I'm getting at is I expect there probably isn't a whole lot to show in a heat map, but for sure there would be some areas. Perhaps not as exciting of a heat map as r/place though.

Thought: # of remaining virgin pixels is a little clouded by a couple things: people making mistakes then whiting them out, and people using default white space as part of designs

(not sure what you mean by # surviving pixels, but this was my first thought)

I'd like to see an overall heat map, yeah. I know that area in the top left quadrant with the four-color paint roller used to be something else that a user and their multiple alts tried hard to get on the Canvas.
