Note: Our weird and wonderful niche Linux distros roundup has been fully updated. This feature was first published in December 2011.

Fed up with the bog-standard Ubuntu, Debian, Fedora and so on? Looking for a distro that reflects your individuality? In this roundup we've discovered no less than 13 of the quirkiest and most useful distributions that Linux has to offer.

They include one distro which is geared towards those with an interest in crime scene investigation, and an OS which is so light it will run on a PC from the mid-80s.

Read on to find out more about each of these interesting distros. Before we begin, however, do note that not all of these operating systems are suitable for everyday use without extensive modification – so consider running them from a Live CD/USB or within a virtual machine, rather than installing them on a computer.
