Stonehenge

Splashery stretches a drumhead over this Splash's outline, twelve inches across, and finds the ways it can ring. Its lowest is 373.5 Hz, 84 cents flat of G4, 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.

Tap it for the midsummer sunrise shining through the stones.

Stonehenge is a ring of great standing stones on Salisbury Plain, in England. It was built in stages from about 5,000 years ago; some of its smaller stones, the bluestones, were brought from Wales, more than 200 kilometers (140 miles) away. Its biggest stones stand in pairs with a stone laid across the top, called trilithons.

Stonehenge is lined up with the sun: on the summer solstice, the longest day of the year, the sun rises in line with its entrance. Tap it: the sun comes up over the far bank, framed by the great trilithon, a golden beam shines through the stones, and they glow gold.
