Created by Oliver Postgate and Peter Firmin of Smallfilms, it starred a family of penguin-like creatures who lived at the back of a barn on the fictional Berrydown Farm.
The Pingwing characters were knitted by Firmin's sister Gloria Wilson, and the animation was achieved using the stop motion technique.
The series was in fact filmed partly "on location": since Peter Firmin and his wife lived in an old farmhouse, and the Smallfilms film studio was located in a disused barn adjacent to it, all the exteriors needed for the series were available literally on their doorstep.
A short sequence of Pingwings is available on the CD accompanying Oliver Postgate's autobiography, and a DVD of the 18 episodes is also available, from the Dragons' Friendly Society.
The music for the series was composed by Vernon Elliot, and performed by him with the oboist Sidney Sutcliffe.
