Marble Bath brings the centuries-old craft of Ebru to a virtual water bath. You do not apply a marbling filter, you actually marble: drop ink onto the water and every earlier drop yields into a ring around it, hold to let a drop grow, drag to trail it across the surface. What forms is the real thing, built the way marblers have always built it.
Then you work the bath. Draw a single flowing line with the needle, pull the whole surface into feathered ripples with the comb, sway it into chevrons with a wave, or plant a vortex that winds the colours around themselves. Ebru flowers bloom under your hand – a tulip, a carnation, a daisy, their petals raked out of concentric rings on a leafy stem. A gall drop opens clear water inside the pattern, and classic recipes like Stone, Nonpareil and Peacock give you a marbled ground to keep working over.
Because the whole bath is exact mathematics rather than a simulation, the picture stays razor sharp at any export size, and the ink behaves like real pigment: a darker rim gathering at each drop’s edge, faint clouds drifting inside it and stretching as you comb. It drops in as a re-editable generator layer, so you can reopen it any time with every gesture still in place and still undoable. Everything is computed in your browser, with nothing uploaded and no account.
