For more info on losethos, take a look at http://www.templeos.org/ - this is an OS he apparently wrote without assistance.
Losethos's real name is Terry Davis. His video had me awestruck, laughing (he can be pretty funny and relatable), and just all-around amazed at the man's sheer brilliance. I cannot begin to fathom the dedication that it must have taken to create such a piece of software, especially in the face of constant rejection from people on the internet because of his schizophrenia.
It's upsetting how dismissive of his work he can be, he deserves to be proud of this, I certainly would be.
