Color matrix blob.
An experiment exploring if SVG filter effects from this CSS-Tricks article can be used to create an organic look and feel.
Only works in Chrome, thanks to a happy accident in how it handles feColorMatrix values beyond the usual 0-1 range. Firefox and Safari, sadly, clamp them away.
Trying to build alpha thresholds manually via canvas for a similar effect doesn't work either for me, since Safari doesn't support context filters (yet).
Still here, just because it looks mesmerizing.
