Idea

I have an idea for my mouse toy, inspired by fireflies. 'Catching Fairies' there will be circles that float around the screen and the user can draw circles to 'catch' them once they're contained they grow brighter and brighter and move faster until they break out of the trap.



Here is a very sketchy version of what I would like my program to do.

Rather than working with a bunch of circles I think it would be easiest to make fairy objects that have a boolean 'trapped' which says whether they've been caught in a net or not and methods like react() to make the fairy freak out once it's caught and outOfBounds() which makes sure the fairy doesn't go offscreen.
