IceBreaker

IceBreaker is a free software game in a similar vein as Jezzball.

The game involves collecting a group of penguins from an iceberg in Antarctica in order to ship them to Finland as they are essential to a secret plot for world domination. To move them, you must break the iceberg into chunks by creating melting lines in the ice with Special High-Tech GNU Tools. To cut back on shipping fees, these chunks must be as small as possible.

It was included in LinuxWorlds' list "Linux fun for the holidays" in 2000 which was also posted on CNN.
