I for one appreciate your effort to share ideas. I have to say that the first time I saw one of these floating clocks I was amazed and impressed. I remember going to work and having to describe it to the other engineers that worked there. There is an excitement that comes with the first sight of something that is novel and clever!!

This excitement is something that comes to us in a unique way because as an engineer we can immediately grasp "how it works" or "how it is done" even though we had not thought of it ourselves beforehand!!!

I know the first time I saw the idea at the following link I had some of the same feelings of being amazed and impressed. In this case there was also a large amount of amusement that went with it too. Enjoy!! (for those that have not seen this before)

BTW ---- this one does happen to also use an 8051 style part.
