Web design and penguins in this week’s sites we like.

Happy Cog makes a friendly impression with Rooney’s soft slab serifs. Ratio contributes paragraph text and all-caps, loosely letter-spaced navigation.

And Impress A Penguin invites you to work at Penguin Press with Robert Slimbach’s Warnock and a sequence of charming illustrations.

That’s all for this week! Share sites that you like in the comments.
