4D Toys

A playful 4D physics sandbox that lets you explore and manipulate toys from four-dimensional space. Watch shifting 3D cross-sections, rotate through unseen axes, and discover how higher-dimensional objects move, collide, and stack. Blending simulation and education, it turns abstract math into hands-on intuition with tactile controls and visually rich scenes. Experiment with dozens of handcrafted toys and setups, realistic 4D rigid-body physics, smooth touch gestures for multi-axis rotation, and clear visual modes that make complex ideas feel accessible. Perfect for curious minds, students, educators, and anyone who loves to learn by playing.
