Ions 2+ vs Dot

Ions is back, recharged and better than ever! The sequel to the staff-favorite particle simulation allows total control over the look and behavior of your creations. Ions 2+ also supports iPhones and iPods as well as iPads! Your ions can now change color and size based on age, speed, direction, and other parameters! Change shape, leave trails, change the background, and more! Use your device’s accelerometer to react to gravity or add turbulence and drag for more variety. You also have both rectangular and polar grids for precise placement. Why stop at only 20,000 particles? With Ions 2+, you can raise the limit up to 100,000 on faster devices. Of course you can still save your favorite layouts, as well as any custom looks you’ve created. Ions 2+. I'm positive you'll love it.

Dot-Physics is an interactive particle sandbox where tiny glowing dots follow simple rules and grow into surprising patterns. Choose a preset world, create your own rules, or draw particles directly onto the screen. Change how colours attract, repel, chase, cluster, and spread, then watch the world come alive. Features: • Real-time particle worlds with colourful motion • Creative Mode for custom attraction and repulsion rules • Draw Mode for painting new particles into the simulation • Touch interaction for attracting, repelling, stirring, and dropping dots • Adjustable dot count, speed, damping, radius, and point size • Relaxing ambient background music • Presets for quick experiments and beautiful patterns Dot-Physics is part visual toy, part creative sandbox, and part simple science experiment. There are no scores, timers, or pressure. Just start a world, interact with it, and see what emerges.
