There are an infinite number of useless online tools and proofs of concepts. Silk is one of them, it even has an iPad app. It is a cool abstract drawing tool. But it’s very ink-blotty. I wonder if they save some/all of the pictures made to a giant database somewhere so that they can figure out what’s going on with people. I’m sure they do, or someone does. I’m not sure what you will get out of it, but he, data storage is cheap.
