Here we go again with an Aluminium skin for Calendar.app (formerly iCal.app) and Contacts.app (formerly Address Book.app) in Mountain Lion.
Please note these will not work with 10.7 Lion. If you are looking for the Mac OS X 10.7 Lion skins, either scroll down the blog or go here.
I created new images files to go inside Calendar.app and Contacts.app to give them an aluminium look like previous versions of OS X.
These modification ONLY change the appearance of Calendar.app and Contacts.app, they do not alter the actual programming or functionality in any way. It just makes them look Aluminium.
Download the installers here: -

These skins are provided free of charge but please make a donation if you use them regularly :)
Mountain Lion Installation Restrictions: -
Mountain Lion restricts which applications you can install by default. If you receive a warning that this package cannot be opened because it is from an unidentified developer do the following. Go to System Preferences > Security & Privacy > General, click the Padlock to authenticate, then select 'Allow applications to be installed from anywhere'.
Here's a comparison of the leather vs aluminium: -
If you decide you want to go back to the original Mountain Lion versions and you made a backup before you started, do the following: -
1 - Delete Calendar.app / Contacts.app - This can be done in Finder by dragging the application from the Applications folder to the trash can.
If you receive the error 'Calendar (or Contacts) can't be moved or deleted because it is required by Mac OS', go to Utilities > Terminal.app and enter the following command: -
sudo rm -rf /Applications/Calendar.app
sudo rm -rf /Applications/Contacts.app
2 - Copy back the backup of Calendar.app / Contacts.app you made earlier in to the Applications folder.
