If you think that by trimming your tree, decking the halls, and sending off your cards you're ready for Christmas then think again. You aren't truly in festive mode until you've kitted out your phone with a Yuletide theme.
The Santa and Gifts Theme represents an amusing way to skin your Pocket PC during the festive period. It includes a background image featuring a cartoon Santa and one of his reindeer. I'm not quite sure what's happening in the picture but it looks quite funny.
Besides this amusing scene, the Santa and Gifts Theme alters the Windows Mobile Start menu, adding a snowy, blue non-transparent background to the menu. The theme also changes the menu bar colors in Windows Mobile.
Unless you're a bit of a miser, you should find the Santa and Gifts Theme a good way to liven up Christmas.
