This project is the trying to implement fluxus API (and may be the editor itself, later) in Elm and WebGL.
The result could've been something similar to livecodellab, but in Elm.
A video in action at Vimeo.
master branch could fail to work for now.
The first and the latest kinda-stable, yet experimental version, with working examples is tagged v0.1.0 (79e70a6a) (and it is the version used in video).
The Graph structure with the normalization (meshes, textures etc. are stored by IDs) is in the works here.
