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.
