What happened to my old apps in Mavericks?

Episode 1027 (1:42:16)

Reilly from Balston Spa, NY

Reilly upgraded to OS X Mavericks and was surprised at how different looking the apps are. He'd like to get some of the older apps back. Leo says that when upgrading, OS X puts the older apps in a hidden folder, so he can find them if he hunts around. Reilly says there's new effects in Photobooth as well, which are very cool. Leo says that those are really cool, especially the hologram one.
