It is just goof-off nonsense for someone's personal site, not a genuine good idea in UI/UX.

When Apple rolls out the next iPhone with walking figures for scroll bars, I will publicly retract my remarks and wipe the egg off my face.
(Your tone comes off as “rephrasing the original intent of the post as something slightly different in order to have something to whine about.” It’s just a bit of fun to brighten our morning, not a proposal to interfere with your online banking experience)
Just don't go to that site if you don't like it.
Um... why are you asking this? Feels like an odd tangent. The OP never suggested this was a good idea anybody should use.
