Air Display is available in the Mac App Store, and needs to be installed on the Mac that you want to turn into a secondary display.

USE MAC AS SECOND MONITOR FOR PC FOR MAC
Air Display for Mac (US$19.99 in the Mac App Store) is a bit more expensive than its iOS sibling, but it's also more capable than the mobile device version - especially if you have a second Mac with a large screen. Now Avatron has made Air Display even more useful by creating a Mac app to do the same thing. As we described in a First Look back in May of 2010, Air Display turns an iOS device into a small wireless monitor that can be used to display app windows from a Mac or Windows computer. One very popular and fun iPhone / iPad app that I love to use is Avatron Software's Air Display.
