[kali]

monkey pox??

[Walks @ 7]

Very interesting and maybe the hand of a gorilla?

[Boxplayer]

Tree bark.

[Annie D]

some type of tree bark?
I did think tortoise but it is very lumpy - unless maybe it's a leg

[Issi Bannerman]

Now then. Rhino skin?

[Julie Duncan]

I was thinking rhino skin, too.

[Humphrey Hippo]

I thought tree but the regularity of it makes me wonder.
Very cool. :)
My 3D brain says 'voronoi pattern'.

[marius popa]

Nice texture! A dinosaur?:)

[haskar]

Great textures. It's probably the skin of a fish.

[Joanne Diochon]

Ostrich or crocodile skin?

[Delwyn Barnett]

Fabulous texture, but no idea what it could be!
