The CraftStudio Voxel Model Viewer was created by Sparklin labs – a game company from France. The WebGL demo currently only supports 5 models but this may change in the future. The demo promotes CraftStudio – a multiplayer platform to create (voxel based aka minecraft inspired) games and interactive movies. While there are many so-called “minecraft clones” out there, I think CraftStudio holds promise.
