+# BigScreen
+
+BigScreen is a multi-device display system that combines multiple phones, tablets, or laptops into a single large screen.
+
+## Concept
+
+Place several devices side by side and BigScreen treats them as tiles in a larger display. Content flows seamlessly across device boundaries, effectively creating an ad-hoc large monitor from whatever screens are available. Use cases include presentations, group viewing, and collaborative work.
+
+## Technical Approach
+
+Devices connect via local network and synchronize their displays using a coordination server. Each device renders its portion of the overall canvas. Calibration handles different screen sizes and resolutions. Touch input on any device is mapped to the global coordinate space.
+
+## Status
+
+**Hackathon concept** from the MIT era.
