Has this blog been the inspiration for great artwork? or even mediocre artwork? I have no idea. However there is a painting by some artist named James Shipton with the title Est Quod Est. Funny. Here's a safe-for-work detail; go to the link to check out the "full monty".
Personally I would have named this painting KMWA. But that's just me.
Other possibilities for titles would include Back View of Some Chick Dropping Trou or, seeing that she has her hair in a bun, Bun and Buns. The title Est Quod Est gives absolutely no description of what this picture is about. And that could be said of the blog Est Quod Est as well.
