Did you accidentally upload an unfinished version of this scene? Nothing seems to be working.

clock has no hands

I guess you guys are just not seeing it. I added an explanation to try and help.

I don't know if you are seeing this, but the time setting number boxes that are directly under the "hours" "minutes" and "seconds" colored boxes are invisible because the text color is the same as the background color. If I manually change the text color to white, then I can see the numbers.

Those hidden output boxes were for troubleshooting. Hours, minutes, and seconds are set with the "h". "m", and "s" keys which cause the bright part of the respective rings to move 0.1 rev/sec. The rings run independently, so the digital conversion fails after adjustment. The clock will still work as an analog clock. For the digital conversion to work, the (3) rings need to be keyed together in the right ratio.

Okay, now I understand it. You did a great job on the scene overall but I would not want this type of clock on a wall in my house!

I initially didn't give an explanation because I thought people could figure it out, but that would mean they need to know how Moire effects work, how to read an analog clock, and have an attention span more than 10 seconds. When I read the comments, I figured "Everybody gets this except for Xray and Algodooper" (I really figured "If Xray's not getting this, then hardly anybody is"). Thanks for responding, sticking with it, and checking it out. I don't think anybody wants a clock like this. It seemed like a good idea at the time... Maybe I will make another version.

I know what Moiré patterns are, and when it comes to interesting things like science and other techy subjects I have a very long attention span. And of course I can read an analog clock because I'm (way) over 40 years old. What threw me off when I first ran the scene were three things: 1. The Moiré patterns were changing so slowly that it didn't seem like anything was happening. 2. As algodooper noted, the clock is missing hands. That assumption was made because there is a central pivot where hands would normally be attached. 3. I assumed the digits in those hidden boxes were not displaying because of a coding error on your part (I should know better after playing your scenes for over ten years!).

After making this scene I searched "vernier clock" and came across US patent 2,293,459 titled "Watch" which states "This invention relates to a watch in which the minute and second hands are replaced by a single rotatable disc having vernier markings.".
