I love everything about this. A ridiculous web art project spawns another even madder web art project with secret codes, all in the name of just having fun. I can't help but think, after reading Fancy Bear goes phishing, that these "teens" could easily have scratched their itch by writing a worm or a massive DDoS machine. Instead, they did this.
A few days into making One Million Checkboxes I thought I’d been hacked. What was that doing in my database?
A few hours later I was tearing up, proud of some brilliant teens.
