Dock Pong
MacOS's Dock typically does little more than offer quick access to apps and files and let users know when they have a notification. Developer Neil Sardesai has decided to change that. His Dock Pong uses the NSDockTile class to place a playable version of the gaming classic into the Dock. Sardesai has yet to release his creation, although he notes on Twitter that he would like to in the future.
