Sent this to my dad, and can't wait to talk this weekend. When I was a kid we would tinker around with watches in the basement but, alas, I had different interests and never really got around to truly understanding these mechanisms. I don't really know web development beyond setting up basic pages, but how the CAD was integrated into this is wonderful and I'd love to see more posts going through things like human joints or ICE, or maybe weapons ... other things where we kind of intuitively grasp how they work, but don't know the details. This entire blog seems to do a lot of that. So cool.
