Commander Keen in Invasion of the Vorticons is a three-part, episodic, side-scrolling, platform video game by Ideas from the Deep and published by Apogee Software in 1990 for MS-DOS. Tom Hall (pictured) designed the game, John Carmack and John Romero programmed it, and artist Adrian Carmack assisted. The game came about when Carmack found a way to implement smooth side-scrolling on IBM-compatible PCs, and Scott Miller asked the team to develop an original game within three months. The game follows Keen as he runs, jumps, and shoots through various levels, retrieving the stolen parts of his spaceship, preventing an alien ship from destroying landmarks, and hunting down the aliens responsible. Released through shareware, sales were strong and it was lauded by reviewers for its graphical achievement and humorous style. The team continued as id Software to produce another four episodes of the Commander Keen series and followed up with Wolfenstein 3D and Doom. It has been re-released several times. (Full article...)

Leopard seal

The leopard seal (Hydrurga leptonyx), also known as the sea leopard, is the second largest species of seal in the Antarctic, after the southern elephant seal. Its only natural predators are the killer whale and possibly the elephant seal. It feeds on a wide range of prey including cephalopods, other pinnipeds, krill, birds and fish. Together with the Ross seal, the crabeater seal and the Weddell seal, it is part of the tribe of Lobodontini seals. This photograph shows a leopard seal in the Antarctic Sound.
