A quick HTML create page created with Gemini 2.5 Pro, using the prompt:
Created with the prompt:
Create a particle cloud visualizer that can change shape, color, and other properties. Make it interactive. Use id three.js and Anime.js. Use CSS, JS, and HTML in a single HTML file. Add sliders and controls to control colors, motion and more. If possible, let me upload particle clouds in various formats, including for Unity. Also, make a pop-up dialog with links to good examples. Import and run when I select one. Make the particles transparent around the edges, fading to solid in the center. Add options to animate the cloud randomly, or in patterns, including speed, transitions, and whatever is fun. (If you think of anything.) Add options for color variations in different ways, including gradients. Allow coloring with a rainbow or rainbows. (Somehow, I don't care how.) Enable morphing from one shape to another. Add an option to make the center of gravity follow the mouse. Add option for galaxy background. Add keyboard shortcuts and a help dialog. Let user save and load their settings. Add options to vary brightness. If something isn't possible, just skip it. We're just having fun! :)
