Ingatan is a clean, intuitive, and highly flexible memory quiz generator. It is perfect for a huge range of applications, including learning languages, remembering physics equations, labelling anatomical diagrams, practising any type of exam question, and reviewing organic chemistry mechanisms. When asking questions, a bias is placed toward those with a low historical grade. An inline symbol menu makes it easy to insert non-keyboard characters. Questions are intelligently organised into libraries, and libraries into groups, and can easily be shared.
The J2DGAMEFRAMEWORK provides the necessary classes to implement a simple 2D game in a window enviroment using Java Swing libraries. This framework also provides a Sprite Collision Manager and a simple GUI template. By using this framework, the developers only concern is how to implement classes, and not the 2D World, the collisions, etc. It uses the Observer Design Pattern. It has double-buffered rendering, simple use of collisions, and user-transparent multi-threading for collision classes. You can move sprites like a vector with speed and angle, and simply save and load your game.
