I realise in the small hours that sub-consciously all I have done is to take a design I optimised by trial-and-error, and made it the basis for a boat instead.
Adolf Hitler and Margaret Thatcher are said to have been people who went to bed wondering how to invade Denmark or the Falklands, and wake with the solution.
On a happier note Paul McCartney ~ who lived not far from here ~ is said to have woken one day with 'Yesterday;' fully-formed, to the extent he could not believe it did not already exist and had to be persuaded otherwise.
Ed. Yesterday his previous drones seemed far away, now it looks as though they're here to stay.
