Nobody needed any of this, which is exactly why it is good: two separate springs so pencil lead cannot snap the two ways pencil lead snaps; a bar clamp you tighten by squeezing and release with a thumb; knitted borders around each window, because a green-and-cream check is easier to find than a title bar; a physics video made to settle an argument two people had on a podcast; and an app that does nothing at all until it hears your name.
