The finder is the main navigation tool on lineto.com. It's a tiny window that can be collapsed and expanded to a more detailed view with a navigation bar that shows the current address. Lineto.com functions like an own application with its own windowing system. It takes a little time to get into its logic, but once understood, the handling of the website is very easy and fast.
The lineto finder is inspired by the OS X finder's column view, which we find is very usefull for fast navigation.
