A protocol and toolkit for playing Texas Hold 'em without a trusted authority — secret casinos, if you like.

The dissertation explores cryptographic card-dealing, the challenge of fair play among peers who don't trust each other, and the civic case for a protocol that lets people evade censorship without funding corrupt house operators.

The deliverable is a toolkit for peer-to-peer card games; Texas Hold 'em is the reference implementation demonstrating that the protocol actually works end-to-end.

toroCam puts a dedicated Arduino-compatible board between your phone and your SLR. The phone only hands over instructions; the board reacts to sensor values in microseconds — far faster than any phone-tethered rig — which unlocks the kind of precisely-timed shots you couldn't otherwise catch.

Like this droplet, frozen mid-rebound. The phone is the UI; the board is the shutter.
