Recession or not, the holidays are coming and you will need to buy gifts. So let's make it fun. Among the following ideas we offer up this year, you'll find a memory-stick diamond pendant, a dog toy with historic significance, and a blade-free fan. Sure, the $20,000 necklace won't fit everyone's budget, but nearly half of the items cost less than $50. And we've included seven gifts whose sellers give some or all proceeds to nonprofit causes. Merry Christmas, happy Kwanzaa, Hanukkah, and Chinese New Year, and Eid Mubarak from all of us at BusinessWeek.
