[caksbsas] Large wall clock

Create a large, lightweight wall clock.

Large clocks are better because they are easier to see.

However large clocks tend to be heavy, requiring additional effort to mount to the wall (can't just be a thumbtack).

Dispense with the back and frame and just have hands?

How can we avoid excessive power use due to having to move large hands?  We wish to avoid a big battery.

The much, much more generalized problem: put a moving image on a wall. Many standard solutions exist, but plenty of opportunities for invention.
