Each of these pieces began with an error. Photo paper usually has a right side and a wrong one. Printing on the wrong side makes an inky mess that may take weeks to dry. But an image is there, vaguely, and if another piece of paper is laid on the fresh mess, a contact print can be made. Different papers and successive impressions give variously textured results. When these are scanned, colored, and rearranged, almost anything can happen.
So much did, in fact, that sometimes I misprint on purpose.
