The startup of our own company is in the pipeline and more exciting for me. However, I am also a big fan of this type of thing. Operating system design centric operating systems… MikeOS is:
“MikeOS is a 16-bit real mode operating system for x86-compatible PCs, written entirely in assembly language, which boots from a floppy disk or CD-ROM. It features a text-based dialog-driven user interface, a command-line, support for FAT12 (MS-DOS-like) floppy disks and sound via the PC speaker. It can load external programs and has over 30 system calls. Additionally, basic DOS .COM program support is included.”

Update [27-Mar-2008]: MikeOS moved from Sourceforge to BeliOS and released version 1.2 in January 2008.
