I'm building a feature length AR experience, scene by scene. A piece of theatre about perspective, and how we stopped hearing each other. And how we might fix it. And, through this platform, a piece of theatre you can experience wherever you are. This space will be updating and expanding until it eventually contains the entire piece, and more. Your support couldn't mean more than it would right now. publicvariabletheatre.org
MnemoStack

A spectator freely swipes through a deck of cards on your phone. They stop wherever they want and without you touching the device again, you instantly know the exact card. Built for magicians and designed for live performance, MnemoStack feels natural, organic, and impossible to backtrack. Powered by the principles of memorized-deck magic: Mnemonica, Aronson, Si Stebbins, Nikola, Eight Kings. it creates a moment that feels completely fair, yet utterly impossible. Built for magicians who already perform with memorized stacks and the perfect reason to start learning one. Features • Works with Mnemonica, Aronson, Si Stebbins, Nikola, Eight Kings, or New Deck Order • No forcing, no input, no visible app actions • Instantly know the spectator’s card • Minimal, elegant design for real performance They swipe. You know. Simple. Clean. Impossible.
