User Interface Legend Dies

Jeff Raskin, the intellectual driving force behind the Macintosh, lost his fight with Cancer on Saturday. He was a remarkable man, always trying to improve human-computer interaction; the more revolutionary the better.
His approach to computer interfaces is best exemplified by two things; his book 'The Humane Interface' where he describes his philosophy, and the CAT word processor. While the CAT was a complete flop, it at least represented an attempt at creating something better, rather than just an incremental improvment on the WIMP (Windows, Icons, Menus, Pointer) metaphor.
Most recently he has been working on the ZUI, or zoomable interface. I have dreamt about this interface ever since reading about it. In fact, if I had lots of money to throw away, I would build it. I saw throw away because, just like the CAT, it would be impossible for this evolutionary step to get anywhere in the indentured world of interface design. HOWEVER, maybe apple or MS might copy it...

Strangely, I am more emotional about this than 'Auntie' Nan; but then, I guess I new him better (if vicariously).
