The screenshot tool is so incredibly handy tool. (also known as screen capture on Windows). With the Mac, if you hit command-shift-4, you get a crosshairs to click and drag the area you want to capture.
Today I accidentally dragged the cursor over a very very tiny section of my screen. Just 12 pixels by 10 pixels.

The preview screen on my Mac displays this file as much larger:

Looks a little bit like an eyeball. But instead it’s just a bit of text. The MacOS makes the image a bit fuzzy when blown up.
Here’s the file in photoshop blown up:

Look at how the aliasing in the pixels gradiate in hue from a nice simple brown up to tan then to a light yellow, eventually reaching white.
Typography on computer screens so cool. Over time people had to figure out how to make text look nice on a screen. With all these pixels getting softer at the edge, using other colors to display simple black text.
I’d like to see a skyscraper use those brown to yellow gradation. The Wrigley Building in Chicago has white-glazed terra cotta clay covering the entire building. The higher up the building, the more the white glaze turns a slight blue. Or so I’m told.
