Animated Noise Background with JS and or CSS

[ryanmunger]

I was just wondering if anyone has ever seen an effect like this done with JS or CSS? Or even what something like this would be called, so I can begin searching around.
I’ve searched codepen and have found things similar, but not close enough to this.

Any help would be appreciated.

Hey guys. I feel like I am getting a lot closer with this technique.

After zooming into the gif, I noticed it’s just a bunch of little bars, that cycle through 4 shades (white to black).

This code pen is obviously not very performant at all and has some issues with the timing of cycling through all 4 colors.

I’m just wondering if there is any feedback based on this current implementation.

Here are some things I am aware of:

• Optimizing the effect to go full screen with it (maybe use canvas instead of looping through a bunch of divs using jQuery? (ugh, I know))
• Get the animation of each little “bar” just right, so that it doesn’t reset. Notice all of the “lights” kind of go out at the end of the animation
• Set variables to control the colors and speed
  Again, thanks for all your help. Learning a lot on this one!
