NMS Periodic Table (really pushing lottie here)
I went crazy with the new Lottie integration and made this table of elements.
The only technical thing here was figuring out how to keep the animation looping after a hover animation.
The workaround was having two instances stacked on top of each other. The top one is looping constantly and on hover disappears. While the hover is active the animation follows the mouse X axis. On hover out the top loop becomes visible again. Not too bad.
