A clock that displays the current time in various number bases to help build intuition for base numeral systems through the familiar interface of a clock.

Created it to help my kids understand non-base 10. Also available as a Roku screensaver.

It'd be cool to be able to pin/filter these. Or have Base 10 pinned on half the screen and the other bases swap through the other half of the screen (every 5 seconds or something).

That's really cool, although simple. Thank you very much for sharing that!
