Blink
Version 1.0.1 is a bug fix.
Brief Description:
Blink was developed to help Users who love to work image puzzles (find the differences between two images) but can't find all the differences. Blink is freeware.
When you launch Blink you see the main window.

Preparation for use of Blink is easy. Use Grab (Apple screen capture application found in Applications / Utilities folder) to make a screenshot of each image (use Capture / Selection). Click on the top left corner of the first image, drag to the bottom right corner, and save as Picture1.tiff on the Desktop. Repeat with the second image and save as Picture2.tiff on the Desktop. You are done!
Now, launch Blink and click on the "Blink" button. The differences between the two images will "blink".
If you see a bit of jitter (because you did not make the images exactly the same size or start at the same exact point), just click on the Up/Down and Left/Right controls to minimize the jitter.
You can find image puzzles on the internet by searching for "picture difference game" or clicking on "Image Sources" > "Options" in the menubar and clicking on one of the ten buttons to take you to puzzle sites. One set of images is included in the zip package to get you started.
