Ken Evan and the Three Dimensional Kinef

I really enjoyed some of your some of your books and things that you've written because you put him in real context one of my problems which can Evan for the longest time was I could only see theory with it. So yeah I tried to articulate Kinef in in more practical terms and to draw I drew this three dimensional thing that sort of helped to. Dave actually Dave Snowden revised it for me and said no no it should be like this then they've come up with a much much better 3D version in the new KineF in book that came out recently.
