This is sooooo incredibly cool and amazing. I just noticed that Google has a new image search where you can actually drag a photo into the search box to find similar images. They've posted four images to demo it. I thought that was too easy and dragged in one of my own photos, the one of the quilted rocket ship I just made. Look what it found in 44 seconds. I am all astonishment!

Here's an example of what it does if it can't find the exact image, in this case a close up of a seagull in San Francisco. Kinda funny. It seems to match color patches.
