This is basic level of complexity, where animation is mostly connected to hovering, and element reacting to the mouse movement. No clicking events in this example.
In te second example, we've created a more complex behaviour, where the user can hover and click to engage with the illustration (You can click on the phone)
Last example is adavnced behaviour, where the character is following the mouse coursor, as well showing secondary reactions. We have added click and hover to the two elements above, and a reaction for the clicking on each.
