Building an Infinite GSAP Scroll Gallery with Parallax and Flip Transitions

A detailed walkthrough of building an infinite scrolling image gallery using GSAP, covering three core modules: a scroll-driven slider with per-item parallax using a paused timeline as a virtual scroll position, a viewport-aware reveal system that fades images and captions in using SplitText, and a Flip-powered morph transition that expands thumbnails into a fullscreen detail view. The tutorial explains the math behind seamless looping, parallax offset anchoring at wrap points, scrub proxy easing, state machine guards for the transition, and accessibility considerations.
