Here's a little toy I put up on GitHub that will make a young person in your life smile. It's a secret code generator in Ruby. Run the script with the plaintext and you get back an HTML puzzle page "encoded" using a substitution cypher made up of a randomized subset of the emoji character set.
Open the HTML in an emoji-friendly browser (like Safari) and print it out. Good times, and completely immune to the POODLE vulnerability.
