Great tribute YouTube page assembled by the Guardian here.
And in the main tribute here a moving piece from our friends at Aardman. And something to look forward to:
In his latest Wallace and Gromit film, A Matter of Loaf and Death, to be screened by the BBC on Christmas Day, Nick Park - who cited Postgate's less famous Pogle's Wood as his greatest influence - has included his own small tribute, with the blessing of Peter Firmin, Postgate's creative partner: Gromit's old Bagpuss doll gets thrown in the bin, but mercifully is later retrieved.
