Google on Thursday unveiled Vidnik, a new application designed to allow Mac users to create and upload YouTube videos using a built-in iSight, Firewire or USB camera. Vidnik is a free, open source application that can record, edit, and label videos, and then directly upload them to a YouTube account for public viewing. Use of the app is reportedly quite simple, offering all interface control in a single window, with large, familiar buttons and controls.

In addition to creating custom videos, Vidnik allows users to import video from their hard drive, as well as exporting video created in Vidnik to the Finder.

Google also recently added AppMenuBoy – a hierarchical menu enabler for 10.5 – and the Visigami streaming photo screensaver application.
