About Grant Kot
Grant Kot is a personal website that hosts a collection of interactive browser demos. The demos are physics and simulation experiments, including liquid simulation, soft-body and 2D physics, a 3D fluid test, a space simulator, a web audio synthesizer, a 3D point cloud of Tokyo, and multiplayer voxel and checkbox projects.
Several demos are described as mobile-friendly, including Liquid Layers, Pencil Physics, and the Synthesizer. Some demos have limits. The Tokyo 3D viewer needs a lot of memory, especially in its Points + Mesh mode. The 3D fluid simulation is described as an early-stage test with limited performance. VoxelMash is noted as having a new version in development. Demos for Liquid Crystal are offered as downloads from the author's itch.io page for users with powerful computers. A Liquid Layers Maker and a sandbox combining several physics systems are listed as coming soon.
