Hand City
A little city you steer with both hands - no controller, no depth model, just your webcam.
One hand moves buildings, the other flies the camera, and together they zoom.
Right hand
point your index finger to highlight a building, pinch (thumb + index) to grab it, move to slide it across the blocks, release to drop on the grid
Left hand
pinch and move to orbit around the selected building (or switch to explore mode in Tuning)
Both hands
pinch with both and spread apart to zoom in, bring together to zoom out
press T any time to open Tuning - adjust all sensitivities live, or switch the left hand to explore mode (move = orbit, pinch = pan, like Blender)
