       | adversarial one, intended to jam up facial-recognition other
       | surveillance-related AI. No, nothing so extravagent, just a
       | visualization of internal state.

       | 'Tis still nifty.

       | It just occurred to me that a phone case is probably a really
       | good place to put some adversarial pixels.

         | Yeah, I had the same thought -- I'd much rather have an

         | What kind of adversarial pixels do you mean? Those that confuse
         | AI object recognition software?

         | Looks great but I'm surprised they aren't way noisier. Is that
         | just a result of having a limited number of neurons compared to
         | the number of pixels, or is there some specific trick to it?

       | Regardless, cool project!

         | In a somewhat similar vein, I actually just finished a weekend
