"Machine is rendered entirely using the DOM. During early dev I was leery I’d reaching the end of my rope perf-wise. I expected I’d eventually ditch DOM rendering for PixiJS or canvas when it got too slow. However, I wanted to see how far I could take it

...

I’ve heard comparisons drawn between modern browsers and game engines, with their tightly optimized GPU rendering and DOM / scene graph. The similarities have never felt more apt."

The DOM might have become faster, but using the GPU directly via Pixi is still a world above in terms of performance and using Pixi could have made everything more smooth. But dev time was limited .. and the result is still impressive.

Agreed. DOM started as a prototype and I stayed on it primarily for dev speed due to momentum (and some React DX things -- I checked out the Pixi React binding but decided not to go down that rabbit hole). It's amazing how efficient Pixi is!
