Analogital Clocks

>analog/digital clock idea
-This idea is a way of converting an analog clock into a digital clock- meaning you can read it as a digital clock.
-It involves replacing each hand with a disc of paper (or something stronger- like chipboard or something)- the disc needs to be a circle with a triangle (or slice) missing- that slice allows you to see through to the number that tells you what hour it is.
-The minute disc is a bit tougher. You can't have it read from numbers that are on the hour disc- because the hour disc will be moving. Instead, the minutes must read from the same base as the hours- but then the hour disc must be partially transparent. The hour disc must be made up of a smaller transparent disc, with a solid outer ring. The minutes should say ":25"
-Potential Problems: as the time passes, the missing triangle area (or viewing area of the disc) may be showing a partial number or may be in between numbers, making it impossible to read.
-Solutions: Use large numbers? Eh.
-Fill the entire ring of numbers full of numbers- like :11112222333etc...
Possible variation: have numbers morph into each other in between each number's currect position.
