Seven maps of imagined ground. Seven tones in sand.

Every plate here is drawn by code: the Contour Plates from a recipe and a seed, the Sound Plates from a single tone. Each one is set at full size for posters, shirts, and hoodies.

Contour Plates · I–VII

Seven kinds of ground

Topographic maps drawn by code. Each plate starts from a real kind of ground, from a plateau cut by hollows to a crater on the far side of the Moon, and seeded noise fills in the rest, traced at even heights the way a survey map is.

  • Plate I, Allegheny: tangled gold contours of a plateau cut by hollows, on black.
    Plate I · AlleghenyA dissected plateau of hills and hollows.
  • Plate II, Confluence: two valleys of tight gold contours meeting and running on as one.
    Plate II · ConfluenceTwo valleys meeting, as the Allegheny and Monongahela do.
  • Plate III, Lake Effect: gold contours stretched into long bands from side to side.
    Plate III · Lake EffectContours stretched by a west wind off Lake Erie.
  • Plate IV, Spectacle: peaks and foothills in gold contours above rows of small rings for orange trees.
    Plate IV · SpectacleOrange groves in rows and a road lined with palms, below foothills and snow-capped peaks, as around Redlands.
  • Plate V, Balcones: stair-stepped gold contours of limestone hills along a winding river.
    Plate V · BalconesLimestone hills in stair steps along a spring-fed river, as at Wimberley.
  • Plate VI, Resilience: the straight double lines of levees and a floodwall around a low neighborhood.
    Plate VI · ResilienceA neighborhood below the river, behind levees and a rebuilt floodwall, as in the Lower Ninth Ward.
  • Plate VII, Babalon Working: gold rings of craters large and small across a dark plain.
    Plate VII · Babalon WorkingA worn crater with a small one across its rim, as at Parsons on the far side of the Moon, named for Jack Parsons, a founder of JPL.

  • Drawn live

    The first three plates also draw themselves on the home page, from the same recipes. Press New seed there for ground that has never been drawn before.

Sound Plates · I–VII

Seven tones in sand

Chladni figures from the Sound Plates model: sand on a round plate tuned to A = 432, shaken at seven tones that a popular chart pairs with the chakras, from 396 hertz for the root to 963 for the crown.

  • Sound Plate I, Root: gold sand on a round black plate, in the figure a 396 hertz tone draws.
    Sound Plate I · Root396 Hz on the round plate. Muladhara.
  • Sound Plate II, Sacral: gold sand on a round black plate, in the figure a 417 hertz tone draws.
    Sound Plate II · Sacral417 Hz on the round plate. Svadhisthana.
  • Sound Plate III, Solar plexus: gold sand on a round black plate, in the figure a 528 hertz tone draws.
    Sound Plate III · Solar plexus528 Hz on the round plate. Manipura.
  • Sound Plate IV, Heart: gold sand on a round black plate, in the figure a 639 hertz tone draws.
    Sound Plate IV · Heart639 Hz on the round plate. Anahata.
  • Sound Plate V, Throat: gold sand on a round black plate, in the figure a 741 hertz tone draws.
    Sound Plate V · Throat741 Hz on the round plate. Vishuddha.
  • Sound Plate VI, Third eye: gold sand on a round black plate, in the figure an 852 hertz tone draws.
    Sound Plate VI · Third eye852 Hz on the round plate. Ajna.
  • Sound Plate VII, Crown: gold sand on a round black plate, in the figure a 963 hertz tone draws.
    Sound Plate VII · Crown963 Hz on the round plate. Sahasrara.

  • Play them

    Each figure is one tone. Play any of the seven, or any tone you like, and watch the sand find the lines that stay still.
