A WebmasterWorld thread named Another Weird Holiday Graphic: The Animal Trend Continues suggests that the Google logos have been a bit on the animalistic side recently. The thread creator asks;
Is Google intentionally avoiding more predictable holiday representations, or is it just doing a terrible job?
See for yourself, the 2006 logo:

Versus the 2005 logo:

Ask Jeeves, like last year went with the simple approach.
If you look over the past Google Holiday Logos, the past three have the animal theme. Thanksgiving, of course make sense. :)

There's just too much creativity at Google, I think they should start returning to Earth some time this year. Think more 'in the box.' ;|

2005 logo was probably toned down out of respect for the <b>HORRIBLE Tsunami Nightmare </b> - it was the right thing to do - Google had the Tsunami link RIGHT on their HOMEPAGE - imagine a Happy, cheerful Logo competing ......

The characters in the logo are New York State symbols - beaver and dam; sun over mountains (catskills). Maybe Google is regionalizing it's logo.....???
