interactive audiovisual worlds

Click a world to open it in fullscreen.

World 01

Newton Cradle

Five metal spheres hang from rigid pendulum wires, transfer impulse through the row and react to direct pull-and-release interaction.

Physical, precise, metallic and calmly believable.

World 02

Metal Field

Fifty small metal spheres react to a steerable large sphere and are pushed through the field with physically believable collisions.

Precise, physical, reduced, and elegant in impulse behavior.

World 03

Magnetic Sphere

A calm physical field with one movable magnetic core and 100 responsive smaller spheres.

Magnetic, elegant, focused and believably physical.

World 04

Infinity Swirl

A precise lemniscate made from light points, trails and calmly hypnotic machine motion.

Fluid, technical, dark and focused.

World 05

Geometric Chain

A steerable lead square collects shapes into a flexible chain that releases back into the field on pointer release.

Geometric, precise, technical and cleanly tensioned.

World 08

Solar System

An interactive 3D solar system with planets, moons, orbital paths and controlled depth.

Spatial, orbital, precise and technically poetic.

World 06

Interactive Cloud

A shapeable cluster material made from particles, local line reactions, and subtle signal labels.

Amorphous, reactive, controlled and interface-like.

World 07

Spring Metaballs

An elastic soft-body material made from coupled blobs, spring tension and softly merging surfaces.

Soft, alive, fluid and precisely controlled.
