Keep looking! Linus Åkesson (AKA "LFT") has done A LOT of mind blowing things.
Writing code for the Demoscene? Not good enough. He made his own hardware to run his own demos: http://www.linusakesson.net/scene/craft/index.php
His research into why not all C64's are created equal (and provided a software work around to a hardware flaw) lead to being able to do safe high speed full screen scrolling. And he did it looking at someone else's logic analyzer dump!
