XScreenSaver vs Squooji

The XScreenSaver application is a large collection of historic and educational graphics demos. XScreenSaver is the standard screen saver collection shipped on most Linux and Unix systems. I released the first version in 1992. In 2006, I ported it to MacOS, and in 2012 I ported it to iOS. This application is not a screen saver, of course, since iOS doesn't have those. But it does let you play with the hundreds of graphics demos that are a part of the XScreenSaver collection.

Squooji is a calm, physics-based emoji canvas for toddlers. Tap an emoji from the picker and it floats onto the screen. Add more and they gently push each other around, settling into clusters. Hold your finger on the canvas and they drift toward it. Tap any emoji to pop it. Pinch to clear everything at once. Add enough fish and the screen turns into an ocean. Gather stars and you're floating in space. Five different worlds emerge naturally from play—each with its own colors and physics. There are no levels, no scores, no sounds. Simply a clear canvas and 100+ familiar emojis. Supports fine motor development: Small touch targets encourage accurate tapping over swiping. Pinch, drag, and tap gestures build coordination through play. Parents can join in: Try prompts like "find all the animals" or "pop the yellow ones." Or build scenes together: create a farm, make an ocean, grow a garden. - Designed to be calm and non-stimulating - Works offline - No ads, no tracking. - Great for ages 2-5.
