Some interesting concept and transformation drawings of a selection of Transformers Alexander Kubalsky was involved in, in recent years.

I particularly like the Hound transformation diagram, showing exactly how the parts would need to be designed in order to work.

Some keen eyed people will note that he's actually Australian, and was working at TakaraTomy on Transformers (the Hasbro "designers" send over basic concepts & modes, and the Tomy designers actually create the transforming figures). Not sure why he's no longer with Tomy though, as it was nice to know that an Australian had broken right into the "inner sanctum" of Transformers toy creation.
