FrAid (Fr[actal] Aid) is a programming language that is appropriate for mathematical computations, visualization, batch processing, and more. It features both a standalone application that provides a programming environment for the language and a system for integrating the language with Java. The Java interface allows mathematical equations and formulas to be used with Java code, making it easier to process numerical computations, symbolic computations, imaging, CAD, and more.
Wechselspieler is a tool for mapping motion data from a video stream onto sound events in the MIDI and OSC protocols. It features a GUI for easy selection of trigger regions in a video stream and mapping these to individual sound events. It supports various video input sources, such as Video4Linux devices, movie files, and FireWire cameras. As output, it supports ALSA based MIDI devices and the UDP based OSC (OpenSoundControl) protocol for integration with MIDI hard/software and OSC-capable software like PD, SuperCollider, and Max/MSP.
