X-Plane is a flight simulator that reads in the geometric shape of any aircraft and then figures out how that aircraft will fly. It does this via an engineering process called "blade element theory", which involves breaking the aircraft down into many small elements and then finding the forces on each little element many times per second. These forces are then converted into accelerations, which are then integrated to velocities and positions. This gives X-Plane the most realistic flight model available for personal computers.

hanjadic is a program that displays Chinese-based Korean characters ("hanja"), their Korean pronunciations, Korean and English definitions, their radicals, and related Korean vocabulary derived from the Chinese. There are four ways to search in hanjadic: English, character sound, character compounds (words composed of multiple characters), and by character. Despite its name, it probably isn't that good as a dictionary and is better suited as a Korean etymology and vocabulary-building tool, though it is also designed to show the beauty of traditional Chinese characters.
