Is there a way to slow it down on fast connections and or a video of this? I have an academic interest and am curious how they did this, but don't have an easy way to demonstrate it to myself as I don't currently have a connection slow enough that it doesn't render instantaneously.
Both Firefox[1] and Chrome[2] (and, presumably, Safari and Edge?) have a network throttle in their dev tools. Apart from that, you can use OS level throttling, e.g. Network Link Conditioner[3] for OS X. Couldn't see any incremental rendering on Fefes Blog though.
