It's an project made with Smalltalk using the TV3D engine. So far it's
got examples of how to implement land, meshes, lighting, Sky (boxes and HLSL),
animation, movement, basic collision detection and physics. It also demonstrates
how the properties of each instance can be changed.
Small talk seems to be a development of a language of the guy who coined the phrase
'object oriented' (and wasn't thinking of C++

). It can compile to a single exec
with all assets included.
The interesting thing is that the author says he has released the source code.
However you need to have Smalltalk v6.1 Beta 2, which is only available for the
paying professional license holders atm, although after the beta trial a free community version
should be available.
For the TV3D community, it could be helpful to see the source for info on how to set
up physics for some developers for example. You may be able to use the current community
version to view the source code. I had a look through the .pac files and there is some
source in there, but I didn't have time to see if it was complete.
I think it's an interesting project, that would be great if it continued to grow. It
could possibly turn into a full blown scene or even game engine / creator.
