The Lightweight Java Game Library is a native binding for OpenGL and OpenAL written with game developers in mind. It allows the full OpenGL and OpenAL APIs to be exposed without the penalties associated with competing methods, nor the limitations of APIs such as Java3D. Tutorials and demos are available, and Windows, Linux, and Mac OS X are supported.
MiGLayout is a versatile and flexible Swing and SWT layout manager. It uses string constraints or API type-checked constraints to format the layout. Strings are both short to type and easy to understand. MiGLayout can produce flowing, grid-based, absolute (with links), grouped, and docking layouts. It was created to be to manually coded layouts what Matisse/GroupLayout is to IDE-supported visual layouts.
