Today’s invention is intended as an amusing variant on a digital clock.
Instead of having the segments in a 7-seg digit flash on or off, each of these would fade gradually ie in an analogue way.
This would be emphasised by the use of two colours for each segment, say red and green.
“1” would always be wholly red and “2” green, etc.
As 1 changed to 2, the overlapping segments would appear in a varying intensity of yellow (as shown for 1/2, 2/3 ,3/4 and 4/5).
