Muxic is a minimal user interface to XMMS2. It is inspired by Winamp Classic's windowshade. It is only meant for controlling and monitoring playback, not for managing a media library or even a playlist. To actually play music, it relies on the XMMS2 (the X-platform Music Multiplexing System 2) daemon, and another XMMS2 client must be used to put some music in your playlist. Muxic's keybindings are based on a subset of Winamp Classic's keyboard shortcuts. Muxic announces track changes using Growl.
libNUI is a hardware accelerated GUI framework that makes it possible to build rich multi-platform applications based on 3D rendered dynamic layouts. Interfaces are built as a composition of widgets and behaviors, and the framework handles positioning, resizing, anchoring, and texture stretching. Objects are connected with synchronous events and delegates for mono-threaded communication, or asynchronous notifications and message queues are used for multi-threaded applications. It also supports strings (including Unicode), paths, files, data streams, fonts, threads, critical sections, audio buffer rendering, and more.
