A Decart Lucy 2.5 app turns a finger frame into a live AI scene at 30 fps

A GitHub project and live app show a real-time AI world inside a finger-framed box.

Users hold up both hands to frame an area, and Decart Lucy 2.5 generates the scene live at 30 fps. Unlike offline video editing, the output tracks motion in real time: if you blink, it blinks; if you wave, it waves — with tens of milliseconds of latency. The repo also contrasts this live AI mode with a local-effects demo and an offline restyling workflow.
