What I'm impressed about isn't just the work he's done - which is very impressive - but his ability to explain it. That skill is a very important skill to have. He's written many other articles about his work: http://rsnous.com/index.html http://rsnous.com/index.html And they all are great reads. I'm sure being able to explain his code has contributed to his skill as a programmer as well. Well done, Omar.
