KaleidoCurve vs Two Links Double Pendulum

Doodle up complicated patterns from simple curves that you can go back and edit, or save as copies. Create new sequences of color gradients that apply to each rotated version of the curve. Drag out a smooth bezier curve with the pen tool and you can edit as you go. Explore how simple shapes create complicated patterns. Curves and gradient color sequences can be saved as named files and reopened for editing. Become familiar with Bezier parametric cubic curve drawing as used in popular vector drawing programs and try out the options to edit point types and handles.

Two Links brings one of physics' most beautiful chaotic systems to life. Watch a double pendulum swing, twist, and spiral in real-time 3D — then place it on your floor in Augmented Reality and walk around it. Features • Real-time double pendulum physics (RK4 integration) • AR mode — anchor the pendulum on any flat surface • Orbit the 3D scene freely or let it run hands-free • Adjust link length, pivot position, density, and color • Particle trail from the second link tip • Night sky environment with the Moon and Earth • Pause, shuffle, and watch the chaos reset
