Velocity Marquee
An onboarding screen for an invented photo app, on warm off-white paper with a fine grain. Under a small mark and the "Afterimage" wordmark, three rows of rounded photo tiles tilted about 8 degrees, rising to the right, run as endless marquees, the middle row the other way. Below them sit page dots, a short semibold headline with a line of body text under it, a full-width black "Get started" pill and an "Already have an account? Sign in" line. Swiping through the three pages throws the rows with the finger's speed: they race, the tiles lean into the motion like italic type and stretch, then ease back to the idle drift while the headline slides across to the next page and the wide page dot moves with it.
