Microsoft Research has developed and released Singularity, a non-Windows operating system platform. This OS is available for download at

Singularity is focused on the construction of dependable systems through innovation in the areas of systems, languages, and tools. Singularity a research operating system prototype is aimed at extending programming languages, and developing new techniques and tools for specifying and verifying program behavior.

Singularity uses type-safe languages and an abstract instruction set to enable Software Isolated Processes (SIPs). SIPs provide the strong isolation guarantees of OS processes (isolated object space, separate GCs, separate runtimes) without the overhead of hardware-enforced protection domains.

If you are in High School, Singularity OS would make a great Intel Science Fair project. Students looking for a thesis of some sort, this operating system is sure to interest you and If you an instructor looking to add some sparkle to your Operating System class, this might be an interesting addition or extra credit project.
