There's a good obituary on the BBC website.
The blogosphere is already, unsurprisingly, awash with appreciations of Oliver Postgate and his work: where would we be today without Noggin the Nog , Ivor the Engine or The Pogles?
I was too old to appreciate his most popular series - Bagpuss - when it first hit the screen, but my children have certainly made up for that in subsequent years: the 'Complete Bagpuss' DVD still makes an appearance occasionally, and not just at the behest of the 7-year-old!
