Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

The Orb: a parametric trackball with BTU mounted ball and keyboard switches for buttons
But I doubt any of this will ever run on the GPU... Multi-threading on the other hand, is already implemented and it works on the Gamma side, but I had to switch it off by default because CGAL doesn't seem to be there yet (see here for more). It does mostly work though, at least for the polyhedral operation which is what matters, although it may not be the great speed-up you expect it to be.

A clamp mount accessory for the Lagrange
I was looking for a suitable example for a tutorial for my programmatic solid modeling CAD Gamma and a clamp seemed suitable. Well, I haven't started work on the tutorial yet, but here's a clamp-mount assembly for my Lagrange keyboard.

Gamma: scripted CAD with Lua and Scheme language support
It's currently quite stable and can be used productively if you can manage to build it. It should support many platforms, but currently is developed solely on Linux. An example of what it can do, can be seen in the Orb trackball. See the project page for more details.

Computational geometry with a Scheme flavor
This might interest the mechanically (or geometrically) inclined here: I've just released Gamma, which, for want of better terms, I'll describe as a geometry compiler. It works like most compilers, only the output is geometry, not executables. It also supports multiple language frontends, one of which is Scheme (via Chibi-Scheme, the other currently being Lua).

The Orb: a parametric trackball with BTU mounted ball and keyboard switches for buttons
The Orb was designed as a relatively complex application that could drive the development of Gamma, which, for lack of better terms, I will describe as a multi-language compiler collection for computational geometry. You write programs in one of the support languages (currently Scheme and Lua) and it produces geometry. If you're into designing stuff and have some programming skills, have a look at the project page for more details.
