Kaleidoscope for Mac is an interesting new file comparison utility. It looks to be a great tool for both web developers as well as designers, and as far as I know it’s the first utility of it’s kind to do image file comparison.

The app is super snappy, and there’s lot’s of great little features when you poke around the single-window interface. You can set up multiple comparison sets with tabs, and add any number of files per tab.

The image comparison tool supports JPEG, TIFF, PNG, PSD and more. Compare files using Two-Up, One-Up, Split & Difference.

The text comparison tool will work with any text file: plain text, source code, HTML, etc. Choose from three layouts: Blocks, Fluid & Unified — and it even imports text from .doc and .rtf files. You can quickly jump from change to change and the app will highlight all the added, deleted and changed text.

And if you’re an advance geek, it also supports Subversion with integration for Git, Mercurial, SVN & Bazaar as well as Versions, TextMate SVN, Cornerstone, and the ksdiff Command-line tool.

There’s a 30-day demo, so give it a download and see if it’s worth the €29 (about $35) to you.
