The occupants of the Bay of Fundy may want to build a larger one.

I have built multiple clocks which can pump out the tiny data bits but how best to dramatize the height of this transition except to build a clock that moves with the height of the tide! I chose a very big bobber to indicate the current tide height and its movement is controlled by a stepper motor connected to a timing belt which can be cut to any length-in this case 35 Feet! Depending on where you live you can customize your clock to whatever tide height you have. Mathematical algorithms are used to find all the points in between because tides are nothing if not local.

The heights are measured relative to a fixed datum point and the zero mark is an average over years of a group of low tides.

NOAA has a tidal station that regularly monitors this excursion. The greatest difference between the lowest and the highest measurement of water that courses by our house each day can be 35 feet! This is an incredible display.a whole ocean bay, miles across emptying out and then returning with a singular wave-a bore tide-that can be surfed on a regular basis. In Anchorage, where I live, we experience the second highest tides in the world. Another clock like device for dramatizing the rolling anarchy of the sea.
