Might be fun to animate one of the escapement gear images and include a pendulum. The tri-bevel-gear assemblies are useful for generating counter-rotating prop assemblies for propellers, drone blades in a gimbal, or ceiling fans by fixing a pair of middle gears to a hollow shaft and driving one of the other two. That's also an interesting mental exercise in topology since initially you're taught c cc c cc c when asked what is the direction of rotation for a particular gear in a series on a flat surface but here you must rotate the surface in mental space and analyze the results to determine direction from an outside perspective.
