Jumping on the minimal graphics example trend,
I made a small 250-ish line long mesh skinning example.
The mesh is defined inside the code, and normals are left out, but it should be good enough to get the gist for anyone trying to implement skinning.

(disclaimer: unlike :d7dealwithit: or :martins: , I do not have experience measured in decades)
