Austrumi is a business card size (the current release size is 93 MB) bootable live CD Linux distribution. It is based on Slackware Linux.
It requires limited system resources and can run on any Intel-compatible system with a CD-ROM installed. The entire operating system and all the applications run from RAM, making Austrumi a fast system, and allowing the boot medium to be removed after the operating system starts.
