Backlit Moiré Effect Clock—Four Design Variations

This clock uses a backlight and patterns to create a moiré effect that will change over the course of each hour. The effect is slow moving but noticible - especially so on the grid faces. Note that you only need one set of hour and minute hands. Multiple designs are included so that you can choose which to use - see animations of their effects below: Large Grid: this is a classic Moiré pattern, allows significant light pass-through and is easier to print.Small Grid: this version has smaller holes so they may get slightly blocked if your printing isn't as precise. However, the larger number of holes means that the patterns may be more pronounced.Rays: this simpler pattern doesn't have as strong of an effect but does let through the most light.Curves: the goal with this pattern was to add some moiré motion (compared to the Rays option) while still letting through the most light.PartsFront ShellBack ShellBaseMinute markerHour marker
