How did he create those demos, did he actually write a windows manager that wraps existing OS functions into his format? The amount of code that would take to give all of the functionality would be stupendous. Also how did he implement eye tracking with such robustness? Could he be kernel hacking and remapping the video memory buffer so that his shim code can take the output of working programs and then rearrange it for the purposes of his demo? Could a designer shed some light for this programmer on how exactly that video was generated. What type of tools would he have used so that I can google them on my own time?

not sure why the downvotes unless you assumed I was sarcastic? I assure you I honestly want to know. As a programmer I only really understand one way to create screen output. Any other mechanism to create demos as slick as that one I would be very interested to learn about. Given that everyone in this thread is completely ignoring how it was accomplished and only talking about the design skill, I feel I am missing a critical piece of information about the process of creating demos such as that. While such techniques may be common to your industry, to those of us outside they appear as magic.
