Tessera Grow
Generative Art for Every Age
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
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).
