The giant cog shows the current hour (1, 2, 3, ..., 11, 12). The minutes are determined by adding up the numbers next to the top marbles of each column (an empty column is zero). The AM designator is used for hours 0–11 and the PM designator is used for hours 12–23. Example: The giant cog shows the number 8 (inside the black ring), the top marble on the first column is 20, the second one is 10, and the third is 4. Thus, the current hour is 8 and the minute is (20 + 10 + 4) = 34. The AM/PM cog is tilted to PM. Therefore, the current time is 8:34 pm. @Greenyman, the owner of the OG project, said that he would say this is the most fun clock to watch. He also said that it was a lot more entertaining than two/three hands going around in a circle, and there was no offense to the people who made those traditional analog clocks.
Thanks to @Greenyman for the ultimate marble clock! When I first saw his project, I became interested in it, and then I remixed this project to make a modified version of it! I recommend watching this at the transition to a new hour. Credits to DJVI for his amazing song Cycles! PS Cycles is also the 9th official level in Geometry Dash! PPS I made the second hand smoother :)
