I am writing one by one now
It’s very frustrating
And there can’t be many petals. How can infinitely many petals be generated when there are only a few? Can it be achieved without canvas?
Or how can it be achieved with canvas? Woolen cloth

Just find some pictures of petals and use js to control the rotation to different angles

layabox, phaser, particle effect

Multiple petal pictures, use js to randomly generate petal positions and petal rotation and select petal pictures.
