Curious Critters presents majestic, cute, and sometimes ominous animals photographed in nature, accompanied by an acoustically based digital soundtrack. All images are captioned and the user may control placement and type size. The excellent screensaver engine provides options for adjusting the delay between picture changes, showing pictures full-screen or at original size, muting the audio, using up to 23 transition effects, and taking advantage of Microsoft Plus! support. Tray- and desktop-based screensaver controls (which work with any Windows screensaver) are bundled as a bonus.
