Sweet Bonanza

Sweet Bonanza is a marbling bench where each drop of ink and each pass of a comb is drawn from its own deformation formula, so the pattern 🔢 on the bath is the exact sum of the moves you made. Below are the ways people put it to work.

For the marbler learning the classics: open the book 📚 of twelve traditional patterns, from Stone and Bull's-eye to Nonpareil, Peacock, French curl and Spanish wave. Each one is written as a numbered pull, and a scrubber steps the swatch through it stroke by stroke. Load any recipe into the trough and it floats there ready to change.

For anyone curious about the maths: tap 👆 a step and Sweet Bonanza shows the formula for that drop, tine line, wavy tine, circular tine or stylus curl, with alpha and lambda dials and a live curve of how far the ink shifts at each distance. Turn a dial and watch 👀 the bath redraw.

For practice 🏋️ between sessions ⏱️: the drill renders a pattern 🔢 from a hidden recipe and asks which pattern it is, which stroke came next or which tool 🛠️ made it. Answers come with the step explained, missed questions collect in a mistakes list, and a weekday streak keeps count.

For matching colours you already love: take a photo 📸 or pick one from your library 📚, drag ✋ up to five reticles over it, and save 💾 the colours as a palette for the next pull. The photo can be removed at any time.

Finished pulls hang on the rack, where you can name them, mark favourites and reopen them in the trough. Sweet Bonanza works fully offline 📴 and asks for no sign-up.
