Well perhaps a dial more than a twist, a telephone dial that is. Arduino forum member Msquare has created a fascinating and somewhat portable guessing game that uses an old telephone dial for a form of input. The game is to guess the number displayed with the LEDs in binary, and the user dials in their answer.
It's an original design and also offers a method to learn how dials can be used in general and perhaps applied to other forms of project. For example with a GSM shield you could work on a mobile device with a rotary dial.

If you're looking to learn about Arduino development platform and how it interacts with external devices, you can't go past "Arduino Workshop - A Hands-On Introduction with 65 Projects” by John Boxall.
Arduino Workshop takes the reader from having zero knowledge about the Arduino platform, electronics and programming and leaves them with the know-how and instructions on everything from blinking an LED, to robotics, wireless data, cellular communications, motor control, sensors, Internet connected systems and more. For more information including a sample chapter and table of contents, visit the book page.
