On the top row, odd harmonics:  f, 3f, 5f, 7f,   ...    , 19f
On the left column, even harmonics:  f, 2f, 4f, 6f,   ...   , 18f


Are you sure about this? If this would be the case, then you should not have all those circles in the diagonal. Hmmm ...

Good catch!   :-+
Mistake deleted, my bad, sorry.

In the attached animation, both the rows and the columns have all frequencies, from f to 10f.

It seems as though the moon is tidally locked or something.

A look back at EV racing over 3 years ago in Canada:

At 1:04, how many names do you recognize on the sign?
At 1:41, I think everyone here should recognize what car it is and why it's special.
Cryptocurrency has taught me to love math and at the same time be baffled by it.

Cryptocurrency lesson 0: Altcoins and Bitcoin are not the same thing.

Is it just me or does she appear to have left the factory missing a crucial piece of software?

This happens when you hire an engineer to dispose of a dead whale.

In 1970, Lou Reed, wrote "Satellite of Love", released in 1972. In the song he predicts:

Satellite's gone way up to Mars
Soon it'll be filled with parkin' cars


That begs the question: how many cars (rovers, vehicles, whatever) do we already have parked on Mars?

Wow, cool!  I didn't realize before that stretching a plane of 2D squares in a 3rd dimension would be the same as cutting a hole in an array of non-stretched volume of cubes.   :o
