Something about idents that gets me really nostalgic and slightly melancholic. One of my favourites was the old C4 one that was just made up of coloured blocks sliding in over a black screen, and before Gazetta Football Italia it would changes to red, white and green blocks. It was because they are the colours of the Italian flag! ha ha. Remember that?
Also, the BBC balloon was good, much better than the current ‘everyday folk’ crap.
