Hey, someone talked about PA in 3D via Oculus Rift. Why stop there? What about PA-bots in real life. Like the idea of PA as a bord game ;-) This is pathfinding and AI on real robots: Snierke
Why not go further and build a functioning, full sized Commander? Interstellar Von Neumann machines that casually destroy planets? What could go wrong?
Real life boom bots. 'Nuff said. Don't like your neighbor? ... No worries, just take this boom bot, and blow his house and mind!
