Toorox is a Linux live DVD based on Gentoo which starts as bootable media using KNOPPIX technology. It is designed for ease of use, with a simple control center and a hard disk installer. It contains many applications and uses KDE, GNOME, or XFCE as a working environment. A live USB pen drive image maker is also present on the desktop. It is multi-lingual and contains the unstable branch of Gentoo (x86 and amd64).
GeeXboX is a standalone media player Linux distribution, similar to MoviX. It's a small bootable CD that allows you to play your favorite video (DivX, XviD, H.264, MPEG 1/2, VCD, DVD, OggMedia, Windows Media, RealMedia, etc.) and audio (MP3, Audio CD, Ogg Vorbis, FLAC, MPC, etc.) files. It also supports networking, and is able to play media from Windows/Samba share, NFS, UPnP A/V Media Servers, RTP/RTSP servers, or SHOUTcast. It supports TV-out, TV tuners, DVB cards, and WiFi cards. It is based on MPlayer, and can be used on any x86, x86_64, or PowerPC computer. It's easy to modify the source to build your own GeeXboX or use an alternative boot method.
GNUSTEP Live CD contains a lot of software for GNUstep, a free implementation of the OPENSTEP framework (which is also directly used in Mac OS X as Cocoa). It includes excellent applications for RAD (GORM and ProjectCenter). The CD is available for i486, AMD64, Apple Mac PowerPC, and Sun UltraSPARC computers.
Linux Multimedia Player is a tiny Linux-based live distribution that converts your computer into a multimedia player. It supports most of the known formats (MPEG 1 and 2, DivX, WMV, qt-mov, Real, MP3, WAV, WMA, Ogg, VCD, and DVD), acts as an MP3 streaming server, auto-detects the various partitions on IDE, SATA, and SCSI hard disks, and auto-detects sound, video, and network cards. It supports all cards as of kernel 2.6.21. Network support can be configured in the GUI. Options are menu-driven and require no knowledge of Linux.
myOS is a minimalistic, OpenGL capable, GNU/Linux-based system without X. It is a bare bones Linux system, stripped of everything but the files necessary to compile and run OpenGL/C code. It has a simplified directory structure and a cleaned-up internal cross referencing. It has two available variants. myOSx-less fits within a 64 MB RAM disk and features a WebKit based on Trolltech's Qtopia demo Web browser. myOSx is oriented for X11, and its development tools are built around Trolltech Qtopia to produce applications based on the WebKit and for the framebuffer of the original myOS system.
64 Studio is a collection of native free software for digital content creation on x86_64 hardware (AMD's 64-bit CPUs and Intel's EM64T chips). It's based on the pure 64 port of Debian GNU/Linux, but with a specialised package selection and lots of other customisations. The distribution includes the Linux kernel with realtime preemption patches, the GNOME desktop, and a selection of creative applications, covering audio and music, 2D and 3D graphics, and publishing for the Web and print. It also includes Internet and office tools that a creative user is likely to need for their daily work.
