As it's a bit quiet around here, I'll ask a question that I've wanted to know the answer to for quite a while...
It is directed informally to Jim - but if anyone else can chip in - don't hesitate...
I'm sure I'm not alone in drooling over Jim's work... and some of my favourites are the cut-away tyre renderings, such as:

and

What I'd like to know is : how are the woven threads being constructed on the compound curved surface of the tyre? While I've no formal education in perspective construction, I have done quite a bit of self education - but nothing of the complexity of projecting the hundreds of woven lines that Jim has in his illustration. Knowing that Jim is a '2D' guy - I wonder how this is constructed?
I've done similar - but nowhere near as complex projections in 3D software - where it's an order of magnitude easier job to project those lines - although you'd still need to get the calculator out if you are looking to do an accurate match to a real world product.
- but in 2D I'd be lost...
