I tried to make a mobile version of the PICO-8 fantasy console. It's unfinished and abandoned, but this video lives on as proof of how far I got. Had to write a lot of C code for this, and dealt with a lot of difficult issues passing data back and forth between React Native, web views, and web assembly.

Explanatory animation about the Natural Cycles algorithm. I came up with this concept and implemented it as an A/B test for the "How It Works" page on the Natural Cycles website. It generated enough of an uplift in conversion rate that we kept it after the test concluded, until it was eventually displaced by a later successful A/B test result. The animation is powered by React and CSS.
