kaivac.com is giving out a free sample of SmartTowel.

The patent-pending microfiber towel is numbered in quadrants – 1 through 4 on one side, and 5 through 8 on the other. This allows the user to fold the towel and use only one quadrant at a time. When a quadrant becomes soiled, the user can simply fold the towel to the next in sequence using the numbered system.
