Inspired by Op Art of the 1960s, OpEvol takes the geometric play of colors and contrasts and animates them into a moving field of ever-changing, optical, kinetic abstraction. It's for staring at. It's for sending to Air Display. Or an external monitor. Or a projector. It's something mesmerizing to design and watch evolve, or just leave on in the background as art. OpEvol Pro is an auto-renewing annual subscription (price shown in the app). Payment is charged to your Apple ID at purchase, and it renews automatically unless canceled at least 24 hours before the end of the period. Manage or cancel anytime in your Apple ID settings.

Shape them with a full parameter editor, let them react to music through your microphone, and capture stills, videos, or Live Photos. On Apple TV, Physarum becomes a lean-back ambient display you steer from the couch or mirror live from your phone. - Full authoring editor: tune agents, sensing, deposition, decay, colour, post-FX - Audio-reactive: the visuals pulse and bloom to sound - Capture: high-res stills, video clips, Live Photos - Apple TV ambient mode with phone control - Curated presets to start from; save your own
