[NetBehaviour] Facecoin

um - perhaps my "fully" was hubris. The things I looked up were:


	* pareidolia
	* SHA-256
	* digests
	* CCVPareidolia is the phenomenon of (usually humans) "seeing" objects in inanimate things -faces in fabrics, horses or rocks or dinosaurs in clouds. As I understand it SHA-256 is a way of mapping large amounts of data onto expressions of fixed length ( and it is somehow -don't ask me how -used in mining bitcoin)...these expressions are then somehow presented as visuals ( ? Rob ?) which the CCV javascript based software searches for "faces". There's lots of lovely rich reference here - the way these automatic processes are corralled by Rob into creating "portraits" and the way Rob's rather Wittgensteinian
"Artworks are proofs of aesthetic work"
 wraps (in a kind of virtuous loop) the mechanism in a further reference to the bitcoin thing...

I hope I have this right :)

warmest wishes
michael
