And Noach found favor in the eyes of God.
If you notice in the hebrew the word Noach and the word favor (or Chen) are palindromes. As we know from science, when we look at something, its inverse is reflected in our eye. That's why Noach found favor (the inverse of his name) in HaShem's eyes.
R' Ginsburgh brings down a really cool point that the first letter of darkness (chashcha) and the first letter of light (nehora) as written in aramaic spell out Chen. Chen represents turning darkness into light. (see more here: http://www.inner.org/times/kislev/kislev61.htm )
