found art, photos of interesting surfaces and accidental marks that make pleasing "pictures" and might even be mistaken for paintings. Recently I read on another blog about a project of Loughborough University in the UK that is developing an online database of various art topics, including -- yes -- found art, except they call it "found drawings."
They're soliciting contributions so I sent in several of my own found art. I thought these two were particularly like drawings. One of them, plus another that isn't pictured here, was chosen for the database.
If you'd like to send in some of your own found drawings, here are the guidelines.
