This is a helpful guide for all the moves I want her ass to make on my face.

Squiggly ones...

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.

Connect 7 diagonally. Very sneaky sis

You suck at math you dipshit.

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

4 over. 3 down. Mmmmm

It gave me a headache is what it is

It's called a repost, @quantagramm. The concept isn't hard.
Camelspotting
It is for a simple spambot.

The point is... a repost.

He should have learned how to jump as well.

I know this one. Lissajous figures. Made them on an oscilliscope in physics lab

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

I stared at this for way too long

circles at the top (7 options) dictate horizontal drawing speed. circles at left (also 7 options) dictate vertical drawing speed.

'O-scope screens', old Sci-Fi movies always used them to make a lab look 'sci-ency'...
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.
Takila
Simply: the top row and left column are the dots (changing) x- and y-coordinates. Then those are combined and the path is traced.

n.cos alpha + m.sin alpha with different values of n and m...

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

It's about phasing.

Ah, yes! A Hilbert space-filling curve!

Fucking love fractals

This made me really happy to watch
wontsayimsorry
yes
TheMadArtificer
that's a really neat way I've never seen before to construct a space filling curve

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

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

spirograph. It works on basically the same principle.

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

I don't think the bot can read Wikipedia.

Exactly. Lissajous patterns. Good on you!

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

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

And also to spot drift between two supposedly known frequencies.

You are forgiven. I once got more upvotes for a grammatical correction than I did for the comment I made which contained the error.
