Kolibri or KolibriOS is a small open source x86 operating system written completely in assembly. It was forked off from MenuetOS in 2004 and has run under independent development since.
In a review piece on alternative operating systems (2009), Tech Radar called it "tremendously impressive" noting its performance and streamlined code-base. Thanks to its small size, scientists announced that they were able to store KolibriOS on a tiny drop of water using synthetic DNA molecules and infer a functional copy without a single error.
