This is amazing! I love it! I have a couple of random questions. What video mode does the GUI environment run in? Does it boot directly into the GUI or can it run headless as well? Do you have a more detailed overview of the different parts of the OS and its current capabilities?

Hi bananaboy! The system currently boots into 1024x768x32 by default. It uses the Multiboot protocol to request that the bootloader sets a video mode before passing control to the kernel. That allows the system to work in tons of places where we don't have a proper video card driver yet :)
As DAlperin mentioned, it's possible to boot it headless although it's not something that gets a lot of focus since this is primarily intended as a GUI system.
I have some presentation and "code tour" videos[1] on my YouTube channel where I go into great detail about how some parts of the system work. If you would like to know about the SerenityOS internals in-depth, it's a pretty good place to start. :)

Disclaimer: I am not the author, just spent a little time with the system.
You can totally boot without the GUI by passing the "text_debug" option to the kernel command line. If you have Serenity built on your system you can try this out really easily by running:
SERENITY_KERNEL_CMDLINE=text_debug ./run
in the Kernel/ directory.
