A long period pendulum clock, w/electromagnetic escapement.
Here's a short period one:

Interesting. I used to collect clocks, and still have 7 French
mantles, 2 American mantles, and 2 German grandfathers. All 80-180y
old. Think I'm more fascinated with well-built mechanical clocks than
accurate electronic-driven clocks, Mumford's notwithstanding.
I think of more interest to me would be the manufacture of an
interesting/unusual/non-tiny pendulum *structure* that exhibits
unusual (to the lay person anyway) properties, eg, very long period,
or a mix of chaotic/nonchaotic behavior (inspired by the
magnet-driven executive desktop toy, or in a different vein, [1]). I
do have a large high spacious entryway that does nothing but convect
heated air up to warm the 2nd-floor ceiling :-)
