Features
A mosaic of light and color
Twenty unique visual patterns, each with infinite variations. Every session is one-of-a-kind.

Developmental adaptation

Enter your baby's date of birth and the visuals automatically calibrate. High-contrast black and white for newborns, evolving through blues, full color, and complex layered scenes as their vision develops.

Infinite variation

20 pattern types with randomized structure, noise-driven evolution, and per-instance parameters. No two moments are ever the same.

Gentle and safe

Adjustable brightness, optional ambient sound, screen-sleep prevention, and tap-to-pause. Designed for supervised tummy-time stimulation.

Full screen immersion

Edge-to-edge visuals on iPhone and iPad. No ads, no tracking, no internet required. Just pure generative art.

Ambient sound

Optional gentle pentatonic tones that drift in and out, complementing the visuals with a soothing soundscape.

Works as a creative canvas

Not just for babies. Use it as a meditative art display, a visual companion for music, or a calming ambient screen in any room.

The science
Built on vision research
Visual complexity adapts continuously based on decades of infant vision research.

0 – 2 weeks

High contrast black and white only. Large bold shapes. Based on newborn contrast sensitivity research (Banks & Salapatek, 1978).

2 – 6 weeks

Strong B&W contrast with emerging edge detection. Patterns begin to include simple movement.

6 – 10 weeks

Blue hues appear first as S-cone pathways mature (Bornstein, 1975). Bold saturated shapes.

10 – 15 weeks

Full trichromatic vision emerging. Reds strongly preferred. Smooth visual tracking developing.

15 weeks – 8 months

Rich color perception. Symmetry preference. Curvilinear shapes and complex layered patterns.

8+ months

Full color range. Complex multi-layer scenes. Flow fields, constellations, nebulae.

The AAP recommends minimizing screens under 18 months. Tessera is designed for brief, supervised tummy-time visual stimulation. Watch for signs of overstimulation: turning away, fussing, or yawning.
