labs.google.com - Why Work at Google?. Personally, i havent seen a better way of doing this.
Speaking about google, its time for the annual Google Code Jam 2004. With the first prize of US$10,000 - its a very good reason to participate ! Google also promises "Top 50 finalists will have an all-expense-paid trip to Google headquarters in Mountain View, CA – where the finals will be held on October 15, 2004".
