The Friends of Nintendo Humble Bundle is currently available, offering a number of Nintendo Wii U and 3DS games.
I could be mistaken, but as far as I can remember, this is the first time Nintendo games have been available as part of a Humble Bundle. And it’s a great deal — 13 bucks gets you everything, including Street Fighter IV for the 3DS and Darksiders 2 for the Wii U.
