Good idea Steve. It also occurs to me that there must be quite a bit of material (both photographic and written) held my the programme makers and the manufacturers of the polystyrene blocks (not to mention all those who were consulted for the programme). Now that the blocks themselves seem to have degraded to the point of no return it might be a worthwhile project for someone to collate as much of that material as possible.
