Are your artistic talents limited to crayon drawings of stick figures? Good, looks like I'm not the only one. For those of us who peaked at a seven-year-old skill level, here's a holiday gift from a true artist: Google's Dennis Hwang.

Our new themed ad units incorporate elements from past Google logos created by Dennis, to give your pages a little extra flair during various holidays and special events. You can enable or disable themed ad units by logging into your account, visiting the My Account tab, and scrolling down to the Ad Type Preference section to click 'edit.' Check or uncheck the box marked 'enable themed ad units when available' - any changes you make will take effect within 24 hours.

If you've enabled themed ad units, users who visit your site may see themed ad units that are relevant to their geographic location (as determined by user IP address) and the date or season. Depending on your location, you should see the seasonally themed ad units for the winter holidays start appearing on your site soon and remain until December 26th. Here comes one now.

Happy holidays, everyone.
