Pingu game history -
Unless you've had your clicking finger lodged up a sparrow's anus for the past month - or been involved in one handed typing, you can't have avoided the penguin tossing game and its many variants.
This site collects them together and has a reasonable overview of the history. Does a better job than the official press release, which is whimsical to the point of utter unintelligibility.
