It spots the difference, and it’s called ‘Kaleidoscope’
The people behind Sofa just launched a new product called Kaleidoscope. It’s a program that lets you spot the difference in files and compare them to one another. With full integration of SVN, Mercurial and Git it’s a great tool to extend your comparison. There are a lot of programs that let you do this, but the best thing of Kaleidoscope is that it let’s you do this with images. Combine this with the fact that it’s made by the people who gave us Subversions and you’ll know that it’s a product that you have to have.
