If you like that, check out my favorite Cistercian numeral library: https://github.com/hsablonniere/cistercian-numerals

Here's a demo of it in action on the author's blog: https://www.hsablonniere.com/a-clock-based-on-cistercian-num...

I ended up using that library to create a simple Cistercian clock screensaver. My hope was that I'd learn to read Cistercian numbers fluently though I'm still working on that.
