Its note
Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 327.0 Hz, 86 cents sharp of E♭4, the nearest tine on the comb. The next fifteen are its overtones, and each one draws its own figure: sand gathers on the lines that stay still.

About it
Tides are the slow rise and fall of the sea, pulled by the Moon and the Sun. Bar Harbor, Maine, has a range of about 3 to 4 meters, and at low tide a gravel bar appears between the town and Bar Island, so you can walk across for a few hours before the water covers it again.
This block is a kilometer of that shore, from NOAA's coastal elevation models and aerial photographs, with the heights stretched up six times. Tap it to play NOAA's tide predictions for the spring tide of October 28, 2026: about 25 hours in 12 seconds, two highs and two lows. The curve on the plaque is the prediction, and its dot marks the moment shown; the moored boats ride up and down with the water, and small waves move on the surface.
