slide, slide!
Here’s a nifty little feature about Mac OS X that I recently ran into: You can build a decent slide show almost instantaneously. Simply select the files you want to view and ctrl-click (or right-click if you have a 2-button mouse), then select Slideshow from the menu. It defaults to 3 seconds per slide with a fade-to-black between images, but if you move your mouse you’ll see a controller bar that allows you see an index page with all the images, fit-to-screen option, click for previous/next image, and close. Or you can use the Esc key to close, whether you use the controller bar or not.
Pretty damn slick. Just one more reason to love OS X.
