Imagene (Drupal gradient image generator): Example images
The Imagene gradient generator Drupal module generates 1D and 2D gradient images based on [Bézier control points](https://en.wikipedia.org/wiki/B%C3%A9zier_curve) encoded in the file url.
animelion on drupal.org asked me for some example images Here are some!
Use your favourite web developer tools (Firebug etc) to inspect the elements and see the background image url.
With only two colors, you can achieve a lot of different gradients: Linear, cubic, etc.
