Here are ten apps that won't annoy you (OK, Alarm Free might) and are either clever diversions or simply fun toys. All links take you to the App Store. Check out the gallery for a preview of everything I've mentioned. All of these were free when I first downloaded them, as I'm a terrible cheapskate, but several now cost between $.99 and $1.99, which isn't bad.

Ancient Wisdom
Basically just a database of quotes from three philosophers: Lao Tzu, Miyamoto Musashi and Sun Tzu. To make it a little more fun the developers make the quotes come from cute cartoon monkeys. Not exactly genius, but fun and the quotes are, of course, pure gold. Better than a Magic 8-Ball, I think.

Newtonica Player
This simple app has you spin a mesh ball to generate a "beat" that times the pace of the electronica music. There is a surprising amount of depth to the song, simple as it is. I was able to modify the tune a bit depending on my spinning, direction and how long I kept spinning. Terribly simple but fun because of those little tonal surprises.

Fireworks
Wherever you tap your finger a firework is launched to that spot and explodes. Nice little animations, plus it works in landscape mode and offers several backgrounds. The sounds could go further, and the fireworks aren't all that varied, but again, kids love it. Put it in "fireworks show" mode and keep it in your dock for a little fun. Note: at the time I originally wrote this Fireworks was free, but it is only $.99 now, which isn't too much to ask, I think.

xCube
This is just a Rubik's cube in iPhone/iPod touch form. But it is really easy to use, provides several customization options and has an undo feature. If you've ever wanted to learn how to solve the cube but didn't want a big cubic bulge in your back pocket, here's your answer. Note: again, here's an app that was free for a while, but is now $1.99 -- still cheaper than a new Rubik's cube, but more expensive than one at a garage sale. You make the call.
