Instead of the digits on this clock "jumping" to the next number, they would slowly metamorphose to the next number. For instance, the seconds' digit would morph to a new digit each second. The ten-seconds digit would take 10 seconds to metamorphose. For instance, at 35 seconds into the minute the ten-seconds'
digit would be halfway on its way to changing from a 3 to a 4. The other digits would follow this pattern.

A good idea for decorative use, but not practical. What if you wake up in the middle of the night, want to know what time it is, and the clock displays an unidentifiable mix between two numbers where the hour numeral should be?
