Lambda the Ultimate

Designscript seems to be an attempt at a visual scripting system from some Autodesk folks:

DesignScript is a programming language for exploratory design and analysis.

It's intended for people who have never programmed before, through to domain experts. It's more flexible than any other languages you'll have seen. Works on any recent 64bit Windows.

There is a textual language apparently implemented in C#. The visual programming user interface seems to be a plugin to AutoCAD.

The textual language seems to support a form of self-adjusting computation.
