The animation is a little hard to follow because the "balls" get stuck in different places for a while, and the colors aren't easy to distinguish or attribute to certain activities.
Was just about to go to sleep and saw this. Now I'm on YouTube remembering how her could make that ball seemingly teleport, defying time, space, physics. If we didn't have slow-mo to see what really happened people would claim it was magic.
At first I was wondering why the shading of the ball is off - turns out it's because it's not a ball but a rotating "torus" (orbiting ball)... The ball probably would look better if there was a longer period between the last and first phases, but that could reduce the power of the surprise.
My problem with the video is that it doesn't show me what can be done. It shows me that the ball can follow the line and with some magical symbols and lines "other logic" can be "somehow" added. It didn't do anything to tell me what other logic is possible, nor did it explain what the symbols and lines mean. So I still don't really know _what_ can be done (besides a pong game) and I've no idea what most of the on screen stuff even is or means.
I thi to it would work better if it actually showed one ball drop at a time, instead of just quickly generating the same bar/scatter graphs that the original sites show.
The single ball drop, with slower motion, gives you a chance to feel the uncertainty.
From what I can tell, ball lighting doesn't exist. We have lots and lots of people who think they've seen it. But there doesn't seem to be any legitimate footage, which is pretty damning considering there are cameras everywhere now.
I remember what were the effective limits at these times and to me it still looks impressive.
As an example, the observer would never get the idea that it's done by changing "the beginning of the screen" as the grid background stays on the same place all the time, and just the ball (with the shadow) moves.
Also note the change of the rotation direction as the ball hits the wall.
