Procedural GLSL Engine for Seamlessly Looping Vertical Animation

Cosmic Eye is a single-purpose render engine for one phone-vertical artwork. A giant eye gazes out between a heavenly nebula and a sea of fire. A school of koi circles the iris. A marble road runs into the pupil, where a sun and a crescent moon sit side by side, and a small glowing Earth rolls up the road toward them. The whole frame is procedural. No textures, no footage, no AI generation. It loops perfectly, so the 15-second clip can repeat forever as a GIF or Short without a visible seam.
