BA4 QR Real 🍎📷

Bad Apple!! transmitted through QR codes — frame by frame, in real time.

A computer converts each monochrome video frame into compressed QR data. An Android phone scans the rapidly changing QR codes and reconstructs the animation.

• No WebSocket
• No video streaming
• No hidden network transport
• Every QR code contains actual frame data
• Working implementation — not a mockup or template

The QR codes are the transport.

Roadmap

BA5

• Dual QR transport
• Left QR = frame n
• Right QR = frame n+2
• Reorder by frame number after decoding
