Grey on white (or whatever background colour you have) version of the v3 clock, with more attempts to fix the loop bug at 360 degrees. I have removed / hidden the outer ring, because 6 is a multiple of 2 and 3 动画 循环 旋转 同心环时钟没有背景的 (灰色)
This version has been modified from the previous colour clocky clock so that all subclocks have the same face colour, which changes based on what angle the minute hand is at (left = blue, right = yellow, up = red, down = dark green). The date in the middle now rotates in its entirety with the hour hand 动画 时钟 递归 颜色 clocky 时钟 v2
