Yahoo's 24-hour hack-a-thon aka Open Hack Day 2008 finally wrapped up on Saturday evening at the company's Sunnyvale campus. More than 330 developers representing 12 countries attended and submitted 47 hacks.

The Xoopit team, including developer Jerry Su (pictured), won the top prize for Best Overall Hack for hacking the email media manager tool directly into Yahoo's email environment. Nearly 25 prizes were given out all together.

Here are some few fun Open Hack Day highlights:

- 400 pizzas, 106 dozen doughnuts and 20 cases of energy drinks and lots of beer were consumed over 24 hours!

- Nearly 20 tents were pitched on Yahoo!’s lawn

- More than 650 people rocked out to Girl Talk on Friday night
