We are developing an open source 3D system, and what could set it apart from existing tools such as Blender is an interesting question. In our case we are taking a different tack by developing in Common Lisp, which will give us a powerful REPL and whole-system extensibility.

Though the web was a tempting platform, we are keeping it as a desktop app for now. Based on the comments I read here that may have been a wise decision.

We shall see if there is a niche for a system such as ours.
