Here's my attempt to build a better mousetrap clock.
There are two main ways to visualize time: using digital display, or an analog dial. Each one has its advantages: digital display is precise, while analog is more intuitive. Some watches have both displays, but this results in clutter. The clock on this page combines the best of both worlds.
This design can be packaged as a dedicated clock with several "skins", as a feature of a digital picture frame, or perhaps as a screensaver for Kindle or iPad. It may be especially useful in helping kids learn to tell time.
