That is very cool. Wish I had the ability to work out the maths behind that.

there's also another very cool visual illusion is going on.
concentrate on watching middle balls and with your peripheral vision you should see that the lowest ball is turning blue color.

That gives me an idea for DNA strand creation. Very interesting; I can't believe I've never see this.

swinging balls = physics porn?

Obviously, Spacebattleship Yamato has one of these at its core, only using Beryllium Spheres.



Wewt! Mixed sci-fi references ftw!

It's all circles. Sin, Cos, radius and diameters, etc.

Imagine 12 glass discs, side by side, travelling around in a circle, pivoting on a point beside the first disc. The further out the disc, the more rotations each disc has to make to "keep up" with the disc beside it. If you paint a dot on the edge of each disc, the dots will make a similar pattern, left to right (ignoring up-and-down movement), if you look down the row from the pivot point.

The discs farther out correspond to the shorter strings, the near discs to the longer strings

Mind = blown

Oh no you di'int!

He's got balls.
