Neatnik for Mac

From Macroass Software:

Neatnik 2.0 neatens up your Mac Finder desktop by setting the location, size and "View" characteristics of folder windows. These characteristics can all be set by hand, of course, but Neatnik allows you to batch-process the contents of a folder (including all levels of enclosed folders), or an entire disk. For Mac OS 8 users, Neatnik can now set all of the "View" characteristics of each folder it processes. This includes such things as whether "Keep arranged by..." or "Always snap to grid" is set, which column headings are included in list views, the Icon size, and so on. Ordinarily with Mac OS 8, these options have to be set individually for every folder; with Neatnik 2.0, you can set them for a batch of folders (or every folder on your hard disk) at once. Neatnik works on three basic sets of folder window properties: location, size and "View" characteristics. You can choose to change any or all of these characteristics.
