E-Ink Display Clock

An e-ink clock on my friend's desk shows the time in a typeface that changes every hour, cycling through a library of about 200 fonts. You glance at the time and also notice the letterforms in a way you never would on a phone screen. The display refreshes so slowly that you can watch the numbers dissolve and reform, and that visible transition makes each update feel like a small event. E-ink uses no power to hold an image, only to change it, so the clock runs for months on a single charge. I find it fascinating that technology originally built for reading books has found its way into a desk accessory that turns typography into ambient decoration.
