BloBG

BloBG is a Blob Background shader entirely written in GLSL.
It's using a custom Simplex noise implementation as a base which is then used to create the Blobs.
The entire image finally gets some film grain applied to it to avoid color banding.

Update 1: Now with better performance and easier customization!

Update 2: Doesn't use Perlin noise anymore, but simplex noise increasing performance even more!
Also added a new feature to change the color of the blobs and a new color mix mode.
The HSV color mix mode will interpolate the colors in the HSV color space instead of RGB.
