A truly light-weight OS: Written in ASM, with GUI, networking and apps

"It has a nicely working graphical user interface (see the screenshots here).
You can install it in VirtualBox (other VM solutions may work as well, but VirtualBox is the one I tried). It boots from boot-loader into the GUI in around two (2!) seconds! And that's on the VM, not even the bare metal on my laptop.
It feels fast and zippy, even in the VM environment.
It comes with a bunch of games, a web server, ftp server, development tools, graphic demos, a drawing program, a CD player, utilities, etc. Remember, that's all from that 4.4 MB ISO.
Extremely small footprint: After being fully booted with GUI and all, just 10 MBytes of memory are used, most of it probably the video buffer for the graphical desktop."
