The Gradient Swatch Tool and the New Gradient Swatch command in the Swatches panel tool makes it easy to create and apply gradient blends in InDesign. In a gradient blend, one color normally "blends" gradually into the other. But you can also create Gradient Swatches that create stripes, like this:
You can do this in InDesign by dragging adjacent color stops in the New Gradient Swatch dialog box exactly on top of each other. In other words, working left to right on the gradient ramp, you would first create a white stop at 0%, then another white stop at 10%, with a black stop "on top" of the white stop at 10%, then another black stop at 20% followed by another white stop at 20%, and so on.
To make it easier, I've created a sample InDesign file that you can download that contains sample linear and radial "striped" swatches. Download the sample file, and choose Load Swatches from the Swatches panel menu to load these swatches into your InDesign file. To change the colors of the stripes, just change the colors of the "Color 1" and "Color 2" swatches. The file works with both CS2 and CS3.
This is pretty obscure, but maybe someone will find a use for it!
