Presets
Near the speed of light, space and time warp. The Lorentz factor γ = 1/√(1−v²/c²) governs it all: moving clocks run slow by γ (time dilation), moving objects shrink along their motion by 1/γ (length contraction), and energy grows without bound. At everyday speeds γ ≈ 1, so we never notice.

Controls
A moving source squeezes its wavefronts ahead and stretches them behind — higher pitch approaching, lower pitch receding. Push past the wave speed for a sonic boom.
