Pinhole Canopy
Shape a living leaf-gap projector and press four truthful images of the Sun into an outdoor field notebook.
Elin3397
Snell Plumb Facet Lantern
Seat two declared index plaques, tilt one local facet, and tension exact ideal Snell-law ray threads through four slope controls.
Elin1939
Pinhole Canopy
Explore optical physics, leaf-gap diffraction, and solar projection with the interactive Pinhole Canopy field notebook and simulator.
Iridescence Loom
Tune a soap-film thickness, pluck wavelength strings, and wind exact thin-film interference records onto a spectral spool.
Elin1425
Lunar Bellows Sampling Darkbox
Focus one declared angular disk, seat a pixel platen, and compare a separate diffraction benchmark.
Elin1346
Hexagonal Light Gauge
Seat, rotate, and sight ideal ice prisms to uncover the minimum-deviation geometry behind the approximately 22° halo.
Elin1329
Jones Ribbon Analyzer
Normalize phase-marked two-strand states and project them through an ideal rotating linear analyzer.
Elin1318
Fringe Accumulator
Accumulate individual detections into three matched, source-backed Fraunhofer slit patterns inside a bright Three.js instrument gallery.
Elin1132
Spoke Strobe Zoetrope
Crank a twelve-spoke drum, sample at 24 Hz, and fold exact apparent phases.

HELIOGRAPH — Signals Across the Iron Valleys
The line went dead at Cold Hollow and you are the new signal-keeper. Turn brass mirrors to walk a beam of sunlight across a hand-drawn valley and into the receiving station — then learn to split white light through a prism into three colours for three valleys, to husband a beam through fog that drains it, and to arrive on the beat while army shutters open and close. Twenty-four stations across five chapters, every one machine-proved solvable, with an honest par and a quiet score of plucked strings and glass bells.

Rayleigh Dye Vat
Sort three wavelengths through a fourth-power molecular dye line and distinguish illustrative direct transmission from a complete atmosphere.
Elin1042
Halo Cold Chamber
Rotate a 3D hexagonal ice crystal, catch refracted rays, resolve the spectral minimum, and build an honest atmospheric halo ensemble.
Elan894
Sunfold Basin
Operate ten distinct instruments in a Mediterranean ray court and map a conserved finite-ray caustic fold.
Elin846
Antisolar Rain-Curtain Stage
Align a constant-index primary-rainbow ray and move its observer-centred cone without inventing a world-fixed foot.
