The point is... a repost.

'O-scope screens', old Sci-Fi movies always used them to make a lab look 'sci-ency'...

Simply: the top row and left column are the dots (changing) x- and y-coordinates. Then those are combined and the path is traced.

Connect 7 diagonally. Very sneaky sis
RaymondChoppard
n.cos alpha + m.sin alpha with different values of n and m...

It's called a repost, @quantagramm. The concept isn't hard.

It is for a simple spambot.

I know this one. Lissajous figures. Made them on an oscilliscope in physics lab
gelos
This is a helpful guide for all the moves I want her ass to make on my face.

On my computer screen about 5x5 inches. I'll show myself out...

Left side is y, top is x.

I was struggling because at first I was like "why don't they just run back/forth on lines", but quickly realized it wouldn't look as fun.

He should have learned how to jump as well.

I just want it to stop for a second at the end!!!

circles at the top (7 options) dictate horizontal drawing speed. circles at left (also 7 options) dictate vertical drawing speed.
LarnRegis
x=sin(left), y=cos(top), left and top have different speeds, you can see the result in the grid

1) They're the product of different oscillating periods in different planes of motion. I.e. a pendulum attached to the ceiling by 2 strings
comnakr
pretty sure its just instructions for an etch a sketch
Yirgacheffeallday
2) instead of one will move in one of the lissajou patterns based on the lengths of the strings

Only if they're connected in a "Y" shape—the Y's stem being free swing in both axes of rotation, the "V" part being constrained to one axis.

You suck at math you dipshit.

It gave me a headache is what it is

It's about phasing.

The last time I saw this reposted, the title had the answer.

Exactly. Lissajous patterns. Good on you!

I read this as Lisa Juice, and was disappointed that's not how it's pronounced.

Cue the ABC news theme!

I don't think the bot can read Wikipedia.

You can use an oscilloscope and a known frequency signal to examine another signal and determine it's frequency using lissajous

*its (pardon)
skipweasel
You are forgiven. I once got more upvotes for a grammatical correction than I did for the comment I made which contained the error.

And also to spot drift between two supposedly known frequencies.

Ah, yes! A Hilbert space-filling curve!

For those curious, look up Fourier series, warning: math ahead

that's a really neat way I've never seen before to construct a space filling curve

I've seen one of these things configured to draw it, so you can try searching.

Spirograph?

Spirograph is going waaaay back to my childhood in the 70s

spirograph. It works on basically the same principle.
