Introducing my LC version of a well know dynamic optical illusion wherein a number of balls appear to be circling inside of a bigger circle. Cheers,
Roger

Roger.

I like optical illusions, but do not understand this one. The rotating ball group seems to just be rolling inside the large white circle. What might I be seeing?

Craig

Ah, now I see. I needed to show the radii to see what each ball was up to.

My wife and I have just enjoyed that: 1000 times better than
the filthy weather on our winter seaside holiday!

Thank you very much for such a clever stack.

Thanks Roger, very nice.

Kind regards

In Fact this is a computer version of professor Eric laithwaites mechanical explanation of how waves "move" without moving. from his lecture "magnetic river"

I have linked to the actaul place in the video - but if you want to see a real man of science explain things do yourself a favour and watch the lot.

China and japan's high speed trains are based on his work from the 50 years ago

p.s

Better than any of the crap they have on TV these days.

Lagi,

Thanks for noticing the parallels between my stack and wave motion as so cleverly demonstrated By Prof, Laithwait. I love watching the videos that you referenced. Thank you!

Roger

Hi Roger,

If you would add a lock screen to the beginning of the repeat loop and an unlock screen in the repeat loop before wait 5 milliseconds it would run a bit faster and smoother.

I find the circling balls fascinating.

Kind regards
Bernd

And I was so enamoured by your work Roger , I forgot to say thank you for it. I spent a good few hours reliving those “videos” they never cease to amaze me. Some I saw almost 45 years ago some I only saw in the early days of the internet and still some only when YouTube came along.

Thanks again

Lagi

Thank you all for your kind words. And, I am ashamed that I forgot to use Lock Screen. So, I've included that plus some some other cleanup in this revised copy:
Cheers,
Roger
