The following post was made on the Google Mac Blog to announce its release:
I've always enjoyed searching for images on the web, but then it occurred to me that it would be really fun to be able to present the images in a more interesting way than typically seen in a web page. So, I decided to write Visigami, which is both an image search application and screen saver. We're making it open source (Apache license) on code.google.com and I hope you'll have as much fun playing around with it as I did writing it.
Right now Visigami can search from three different image sources: Google Images, Picasa, and Flickr. In the application, there's a search field where you can type a query. Images matching the query will then start animating on the screen. You can animate the images in several ways: fan, carousel, and grid. And there are a few different camera views: fixed, autopan, and mouse pan. There are sliders for adjusting settings such as display speed and zoom. The screen-saver uses exactly the same settings you choose in the application. Although the options panel for the screen-saver works, it's easier to tweak the settings in the application than to run the screen-saver.
Here are some tips on using the application:
* Use your mouse's scroll wheel to zoom in and out.
* While in "mouse-pan" mode, click in the image view and hold the Option key down to move the images with the mouse.
