mobcast inc., headquartered in Tokyo’s Meguro Ward, Koki Yabu, CEO, and a producer of content for next-generation media, including cell phones, has entered the iPhone application market with its release of Photo Aquarium, a game application for the iPhone and iPod Touch, on 31 March 2009.

Photo Aquarium, which is also available from the major US cell phone company, Verizon Wireless, is a popular cell phone game that simulates the care and feeding of tropical fish, using the users’ photos taken with their cell phones as food. mobcast inc.’s 31 March release of Photo Aquarium for the iPhone includes a wide range of additional features.

Photo Aquarium is a game application, where the users raise tropical fish, using the iPhone’s camera functionality.

Whenever the users run the game’s Feed the Fish command, the game activates the camera and then uses whatever photograph the users take as feed for tropical fish, all seamlessly and within the context of the game.

The fish within the game have color preferences, and they express those preferences as they eat the photos players intend as food. By giving the fish a wider range of colors to eat, the users can generate fish in a wider range of colors. A total of 128 different kinds of tropical fish can be generated within the game.

To enable gameplay on the iPod Touch as well, the fish will happily eat any images stored on the iPod Touch, too. As the beautiful tropical fish swim against a background of the users’ favorite photos, the iPhone becomes a decorative accessory for the interior of the users’ home or office.

Admitedly, I don’t get it. So I’ll get it (the app) and let you know what I think.
