I just loved his enthusiasm, as well as the ingenuity of using a length of wire as an acoustic delay line for storage purposes.
The opening shot was a bit of nostalgia as well, when he showed an Original-Odhner mechanical calculator, identical to the one one I have sitting on a bookcase as an example of the calculators we used at school around the turn of 1970.
For us TV types, the use of acoustic delay lines is historically commonplace, though for analogue, not digital storage. From the 1 line delay in a PAL decoder to the massive 3.2ms (MILLI second) polygonal prism delays used in the BBC's world first 525<>625 standards converter.
