The Kunststoff Look and Feel is an extension to the the Java ™ Metal Look and Feel. This makes it very compact in size (approx. 43 kBytes) and ensures that all the great features provided by the Metal Look and Feel do not get lost. It is our little contribution for making the Java ™ platform even better and we hope that it will help you make some wonderful GUIs.

The newest version!
