It's day two of the Market's "10 Billion Promo," in which 10 different apps are offered for 10 days at just $0.10 each. While the official page listing still shows yesterday's deals, a little digging by redditors has revealed 9 of today's 10:

Update: And the 10th app is... Bedtime Battle!

We have yet to figure out what the last one is, and Google has yet to update the promo page, but we'll be sure to update this post when we have more information. In the meantime, hit up the market links and get buyin'!
