Aurorasaur

A desktop browser studio for generative northern-lights artwork. Paint aurora curtains and vortex loops on multi-ratio artboards (16:9, 1:1, story, IG portrait, and more), dial ray style, color ramps, 3D rotation, motion, stars, and dust, then save shapes to a local library or import and export JSON. Exports include opaque PNG, transparency keyed from brightness for compositing onto photography, and seamless looping web clips at 1x–4x resolution. Built-in brand gradients and an AI art-director path help you iterate fast without leaving the canvas.
