Tessera Grow

Tessera Grow is a generative visual art app that creates endlessly evolving paintings on your iPhone or iPad. Like a digital lava lamp, every moment produces unique patterns of light, color, and motion. DEVELOPMENTAL MODE Enter your baby's date of birth and Tessera Grow automatically adapts its visuals to their stage of vision development — from high-contrast black and white for newborns, through emerging blues, full color, and complex layered scenes. Based on decades of infant vision research. 20 UNIQUE PATTERNS Bullseyes, spirals, flow fields, constellations, nebulae, morphing blobs, branching trees, and more. Each pattern is deeply randomized with unique structural parameters. No two sessions are ever the same. DESIGNED FOR CALM Adjustable brightness, optional ambient pentatonic soundscape, infinite session mode, and tap-to-pause. Screen stays awake during sessions. No ads, no tracking, no internet required. MORE THAN A BABY APP Use Tessera Grow as a meditative art display, a visual companion for music, ambient lighting for any room, or a calming screen for winding down. Beautiful at any age. BUILT ON SCIENCE Visual complexity adapts continuously based on research by Fantz (1963), Adams & Maurer (1987), Mondloch et al. (1999), Banks & Salapatek (1978), and Bornstein (1975).
