Thanks for the nice thoughts. I'm a huge fan of all of the interfaces you describe from industrial and commercial applications. I've written previously about my concerns with the touchscreen dominance and the poor UX impact it can have. My day job is to design physical interfaces for all manner of automotive and consumer applications and you could say I specialise in the non-touchscreen design parts.
Regarding the LEGO references, this was just a light hearted look at the problem from a different perspective :).
