The aesthetic of this particular example is absolutely beautiful. I love how visually complex the image of the tree is, while the functionality remains so unbelievably simple (moving the mouse right and left).
The movement involved in this example is great. The continuous looping of everything getting “sucked down” into the center is hypnotizing. It’s almost as if I could just stare at it forever, but if I stare at it for too long I’ll get really dizzy!
The thing I like most about this particular example is the way in which the physics of the balls and chain react to the users interaction with the mouse. Both direction and speed of the mouse effect the way in which balls relate to the space and each other.
