Well, that was fast.This is gloss latex paint on canvas, with ink on gaffer's tape over it. I chose the gloss latex because I've worked with it on some other paintings (which, now that I think about it, I should post here), it blends well, and it has the sheen I was looking for. The gaff tape and white ink were what I originally conceived of, but I went through some other tape attempts and ink colors before finalizing.The 1s and 0s do actually contain a message, but I've decided that this is where I'm going to hide my secrets.
