And pretty impressive that it keeps up the rendering without significantly impacting on my CPU load.

kinda looks like a TV I had which had a broken HDMI port.

I messed up something somewhere with the math/coordinate system/intersecting a bloody sphere, but this isn't exactly a great environment for developing and debugging. Also, I think I may have missed the point...

Nice, you can actually see the overdrive kick in.

It just takes the expression and pastes it into a WebGL shader inside a function. Even a mediocre GPU will be able to push a few sin/cos per pixel these days. (And even a mediocre GLSL compiler should be able to identify common subexpressions and avoid recomputing them. Emphasis on should.)

Looks like something you could potentially create EarthBound-style battle backgrounds in.

The one I tested with worked. (My installation of Chrome failed miserably though.)
-
Literal numbers only work if they have a period in them? Maddening.
FAKE EDIT: Oh, it's fragment shader syntax. That explains why it's so maddening in general.
-
drawing the rest left as an exercise
Aw, that's no fun, you didn't even include a time component!

That one would be for @aliceif …

This is fun. I should waste time with shaders more often.

Show-off. :P
Why does it start with1.0);}? Did you do code injection? Nice one.

Yeah. You can actually expand the "fragmentShader" section on the page, and it will show you the template it uses for the fragment shader (so it's not that hard to figure out...). In particular:
float value(float x, float y) {
return (${value});
}${value}is where the expression is pasted in.1.0);}just gets me out of that function so I can write arbitrary GLSL code directly. (There's a similar fixup at the end of the "injected" code.)

Here's a sneak preview
(bonus mode: scroll your screen)Apparently my monitor's refresh rate is usually high enough that I don't see that at all. I can see perhaps 25 dot-ovals. If I leave the calculation going long enough, I start to see circles. But, taking a screenshot reveals there are many more circles....
Scrolling seems to remove the circles though, not sure what that's about...

It causes me no problems… on a high-DPI screen.

Hmm, I think I have some old HLSL code somewhere that rendered a star and its corona completely on the GPU with Perlin noise, from an old aborted video game attempt. I should try to dig that out later and see if I can adapt it to this.

I'm really surprised nobody has done a penis one yet.

There have been many aliases. The wise man avoids anything that might possibly match, just in case…

Wanted to show you TDWTFers my pulsating

Okay, okay. No need to be so anal about it.

It's an original variant of "laugh as yep" that you adore reminding me about.

@Tsaukpaetra Except the former you actually typed, and the latter I didn't. Also mobile wackiness is different from brain confusion.

@Tsaukpaetra Correct. I did not type 'doing as tell'.
