The BBC has added highlights of that old favourite 'Tomorrows World' to its online archive.
Including this gem; A man who speaks Morse Code... http://www.bbc.co.uk/archive/tomorrowsworld/8009.shtml?all=2&id=8009
I always thought that maybe some of what was wacky and impractical once might just be viable with todays technology so maybe it is worth studying again the programs featuring presenters Raymond Baxter, James Burke, Judith Hann and others.
Tomorrows World was real nerd porn. You just have to love it.
