Hi nice people
If you look "Menger pattern" on the web you will find nice tiles based on menger square formula..
1 Face sponge of Menger, or Sierpiński carpet.

And then i decided to convert a nice fx from Shadertoy , removed 3d part (required some iteration ) for maximum speed..
Try to upload your texture to test this fx;

i seen it, its awesome, i found also triangulation and other cool stuff there, but some of them are just to unusable (high cpu eaters.), but then i used Chrome to preview them, so might be that "chrome did it" awesome work, keep it going
