Probably for the first time, I have noticed an image ad on the Google Results page (screenshot above) - It's a 155px x 240px ad of Google Desktop Search with a wide Windows XP style steel gray Taskbar displayed prominently at the bottom of the Google search results page.
It looks kind of odd on the page and also breaks the layout. Notice the white space on the left side of the ad.
Here's a full version of the GDS Ad on Google Search Page.
