Mac OS X only: When you need a little break from regular web surfing and want some random images pulled from the internets to give you a little creative jolt, you want Visigami, a search-based photo screensaver. Tap a keyword into Visigami (may I suggest “puppy”?) and watch it zoom and pan image results from Flickr, Google Images, or Picasa and send them flying across your screen in one of three random effects. Control the zoom, spacing, and speed of the ‘saver movement, and sit back and enjoy the spectacle. While Visigami is more eye candy than anything else, it’s a neat way to enjoy a montage of photos associated with your search term. Visigami is a free download for Mac only.
