This image was made entirely of push pins. The artist was mad, or obsessed, or needed an outlet. Whatever the reason, it’s more impressive in person. If you happen to be at Grand Central Station in New York City, that’s where you’ll see it. It was drawing crowds today.

In the same space, on the wall, there’s an enormous mural made of colored post-it notes. It had the look of a kindergarten painting, all very cheery and bright. Another cubicle-child at play. Probably a company full. All drawing salaries.

Calvin says, “I can do that with my kibble. It comes in different colors, too.”
