Andrei Kashcha's vector field explorer : Plentiful examples of interesting fields on reddit, compose your own with GLSL, or just click randomize.
Setting the particle color to "angle" and bumping the particle count up to 60000 looks really nice.

Wow, that's super neat. I always like it when people make interesting graphical output easier to program.

Jpfed, that "colorful undulation" one is also nice with an extreme (400000) particle count.

If you do get this far do click on the link and poke around, it's real math but just quite beautiful also and well behaved so unlikely to crash browsers or anything.

Well, I just went and did too much homework trying to figure out how to plot controlled Bezier curves in this thing just to try to spell MeFi or MF or something and now my head *really* hurts.

Wow ... I love playing around with cos and sin, you get so many magical flows:
A couple of my faves:
Colorful rolling hay piles in the field
A virtual drone filming while pacing tumbling red marshmallows
OMG, you can pan and zoom!! .... I've found my mental porn, I'll be in my bunk for the next week.

Panning and zooming!
These are great, please keep posting cool ones as much as you want, Jpfed.

vec2 v = vec2(0., 0.);
I've never seen "0.", with nothing after the decimal point, before...is that a convention in math that I am ignoratnt of? Or is it syntax in a programming language?

Some languages use a period after a number to say "don't store this as an integer; store it as a number that can have a non-integer part (most commonly a floating-point number)".

This is pretty amazing and fun to play with.
