IKI-IKI Phone is a multi-user, networked Artificial Life (= Alife) art game for the I-mode mobile phones. In this sys- tem, subscribed users can create Artificial Life creatures (= IKI-IKI pets), interact with these pets, feed them, take care of them, and evolve them. Networked users can also share their pets with other mobile phones users, trade them, watch them compete against each other, become friends with each other, create offspring and develop an IKI-IKI pet society. Users can also start communicating with each other through their shared pets.
