This is a fantastic idea. Roustem Karimov, who writes ‘Blog From Software Trenches’ had a very cool idea for a post. He’s collecting screen shots of the best designs of OSX Disk Images.
The most common that I’m sure most of us have seen, is from Camino. It’s basically a combination of a background for the Disk Image in its own Finder window, the folders, and icons. The nicer ones give a little helpful info for the less knowledgable, about how to “install” the software.
Go take a look at his post, and the collection he’s got so far. I think Delicious Library is probably my favorite, though AppZapper looks pretty tasty too. And if you have any others to add, leave them in his comments.
