Now, mind you, one must be really (and I mean REALLY) bored to have this site cure boredom. But, the site boasts that feat...so maybe you should check it out and see if it works for you. The Java Balls are for the artist in all of us....the artist that doesn't exactly know what to draw and/or doesn't have any skill. Oh, and an appreciation for spheres is also an extra bonus.
If you have some time to kill, click on the black space in the middle of the screen to start. Then click on the <<>> arrows to change each trait (colour, round, radial, diameter, horizontal light, etc.) of the pattern. (Holding down the buttons will not change any of the traits.) If you really want to mix things up, click on one of the numbers (1-12) at the bottom.
Hopefully, your computer has a fairly recent version of Java software so you will be able to view this.
