OroborOSX

OroborOSX is an X11 environment designed for use in rootless mode with XDarwin on Mac OS X. The source code is also available.Features include:
- X11 windows are interleaved with Aqua windows (the usual rootlessXDarwin implementation brings all X11 windowsin front when one is clicked);
- Clicking in a background window will only activate that window(rather than the click being sentthrough to make something else happen in that window);
- A list of X11 windows is available from the OS X Dock icon (and theWindow menu in OSX10.1);
- New 'X11 application' icons What's New
