Turn any photograph into a mosaic made of dice, dominoes, bricks or beads, then get the plan to build it for real. HarmonicArt is not a filter. It is a studio for designing something physical, and it hands you the material list, the finished dimensions and a printable plan to work from. SEVEN MATERIALS Dice: black and white faces, the classic. Six tones from one set, twelve from two. Dominoes: seven tones per set, laid end to end. Cubes: nine stickers each, six colours, a wall of puzzle cubes. Bricks: studded plates in twenty-two colours on a baseplate. Fuse beads: ironed pegboard pixels. Halftone: newsprint dots in the ink of your choice. Typewriter: glyphs standing in for grey. Pick one and the whole picture changes. The preview updates as you choose. A PLAN YOU CAN BUILD FROM Every piece comes with the part nobody else gives you: • What to buy, by the item, "3,200 black dice, 1,600 white", not a list of color codes • Finished size and weight, before you commit to anything • An estimate of how long the placing will take • The backing board you will need • A printable PDF: a shopping list, a method page, a section map with progress boxes, and numbered section pages with coordinates on all four edges and a per-page material tally Print it, take it to the table, and work through it a section at a time. A STUDIO, NOT A BUTTON • A live preview that redraws as you move a slider, no guessing, no waiting • Touch and hold to compare against your original • Detail from a few dozen tiles to tens of thousands • Several palettes per material, from full colour to greyscale • Three ways to handle tone: flat, diffused or screened • Brightness and contrast, when a photo needs a hand Colours are matched in a perceptual colour space, so faces land on believable skin tones instead of drifting green. SEE IT IN THREE DIMENSIONS Orbit a finished piece as real objects, dice with real pips, cubes with real stickers, bricks with studs, lit and shadowed, before you have bought a single one. KEEP AND SHARE • Save to Photos, or export up to 8192 pixels for a gallery print • A gallery that remembers every piece with its settings, so you can reopen one, push the detail up, switch materials and export it again • Share the picture or the build plan PRIVATE BY DESIGN Your photos are read, mosaicked and saved entirely on your device. There is no account, no server, and nothing is uploaded. Diagnostics are optional and can be switched off in one tap.
