I'm a mentor of the annual Technovation Challenge mobile app dev challenge, mentoring a team of middle school girls that are developing an app to help treat sleep anxiety within their pier group. The team would like to incorporate a "calming jar" animation within their app. Their dev platform is the block coding teaching tool Thunkable, which supports Lottie animations. A "calming jar" is a meditatively soothing visual display that you can search for on YouTube, or use this YT URL to view: https://youtu.be/Mb3ji6fvzEk
If anyone could assist the team by pointing us to some existing work that might fit this solution, or volunteer to be an recongnized support of the team's challenge by creation an animation, we'd greatly appreciate it!
There's nothing you can do in AE to create this sort of animation in a way that it can be integrated elegantly with a dynamic system. At best you could export a huge image sequence created using soem particle system, but that's a nightmare to integrate into any mobile apps for the sheer amount of data required. You better look into genuine native JS based particle systems or Adobe Animate, but even the latter would at best just produce a bloated SVG/ canvas animation with millions of keyframes, not a genuine dynamic particle system running client-side.
