not a font but does anybody know wat this is called ?

Stripes

Seriously, INFAMOUZ KING, this is a font forum, not a preschool geometry one.

It's a square with stripes.

In front the door of my home, there's one like this, we call: "sewer hole"...

ROFL!!!! Yes, yes, that's what it is! Or maybe...skin from a Zebra's eyelid?

The skin of a zebra that ate too many blueberries ?

Or that's suffocating?

A texture.

For the DJs amongst us: Blue Vinyl
