any thoughts on why all the current pix look like dog faces? Is that peculiar to the training set?

Also I think there's a bit more than just ZOMGtrippy. The whole project points out that "if you're looking for it, you'll find it." The system amplifies noise until it sees something familiar. Understanding that humans do this too (to a point), is a critical point in comprehension and discussion of the world, opinions and people. But yeah, it will seem rather "iconic" and dated 10 years from now.
