LMAO!! Not just me then - not sure I've seen him since - ooh - 40ish years ago!
By a weird coincidence, in a series of lectures at work today I saw the use of a 'visualiser' which is essentially an electronicified over head projector - you write on a piece of paper and it appears on a monitor screen to be seen by all. For a deja vu moment and a half - it reminded me of all those old children's programmes' in the 70s like Fingerbob where you saw a hand drawing stuff on a piece of paper.
It's been a 70s retro-sesh for me today.
