About
Nebuloom is a local-first wallpaper studio for building abstract backgrounds from gradients, shapes, and grain. Start with a preset, tune the composition, and export clean PNG, JPEG, or WebP wallpapers. Nothing ever leaves the browser.
A soft nebula core, held by two crossing orbits and three strata bands — the four families in a single symbol.
Bloom core
Radial gradient with grain filtering. Represents soft, layered color fields — the nebula at the heart of the mark.
Orbit rings
Two crossing ellipses at −22° and +32°. Mirrored axes encode Prism; the halo arcs encode Orbit.
Arc bands
Three stacked quadratic arcs through the center, echoing the banded rhythm of the Strata family.
Focal dot
A single bright pixel at center — the fixed point of reproducibility. Everything blooms from here.
Symbolism
A cloud being woven. The bloom is the nebula; the crossing orbits are the warp and weft. Soft matter, held in structure.
Tension
Diffuse gradient, sharp geometric orbits. The tension between atmosphere and structure is the studio's whole premise.
Reproducibility
The center dot is deliberately the smallest, hardest element. Everything blooms from a reproducible point.
Light mode
Dark mode
Both palettes share the same Iris hue family so the accent reads as the same brand across modes. Daybloom warms the canvas with paper and linen tones; Deepfield drops into deep cosmic neutrals.

Nebuloom started as a learning project. An excuse to dig into Svelte and SvelteKit with something visual and self-contained. It also became a testing ground for AI-assisted development, exploring how far you can push Codex and Claude Code as a collaborator on real product work. From architecture to components to the identity system on this very page.
The result is a small, local-first tool that does one thing well, compose abstract wallpapers from gradients, shapes, and grain, and ships nothing to any server.
