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.

Graphics libraries in lisp for game development
CEPL is great for something more advanced.

May: evaluate APL expressions from Clojure
I used to write software for image generators using GLSL and so I used to do some graphics projects using C, OpenGL, and GLSL. Later I discovered CEPL, which gave me a REPL to do GLSL-like graphics pipelines. That was an improvement but I don't find GLSL fun. But then I discovered April and APL in general and now I can dabble with image processing whenever I feel like it with minimal ceremony.

Array programming language(s) for 3d-graphics?
If I was doing a course in computer graphics today I would sidequest with April and CEPL.

(fluxus) – live coding environment in Scheme
Cool! Take a look also at CEPL [0] an OpenGL environment for Common Lisp. Bit more low level, but you can have an OpenGL window open and make live changes in the code, just like anything else in Common Lisp. I can't imagine coding graphics any other way, and is a lot of fun that way too.

cbaggers/rtg-math - a selection of the math routines most commonly needed for making realtime graphics in lisp (2, 3 and 4 component vectors, 3x3 and 4x4 matrices, quaternions, spherical and polar coordinates). [2019]
i had been using baggers' rtg-math while using his CEPL. both worked well for me! OpenGL at the REPL is the only way i want to do it if i have to do it. but i couldn't keep up my interest in using GLSL. the lisp flavor did help some though.

Machine Learning in Lisp
Personally, I've been relying on the stream-based method using py4cl/2, mostly because I did not - and perhaps do not - have the knowledge and time to dig into the CFFI based method. The limitation is that this would get you less than 10000 python interactions per second. That is sufficient if you will be running a long running python task - and I have successfully run trivial ML programs using it, but any intensive array processing gets in the way. For this later task, there are a few emerging libraries like numcl and array-operations without SIMD (yet), and numericals using SIMD. For reasons mentioned on the readme, I recently cooked up dense-arrays. This has interchangeable backends and can also use cl-cuda. But barring that, the developer overhead of actually setting up native-CFFI ecosystem is still too high, and I'm back to py4cl/2 for tasks beyond array processing.
