“Sharelog” graphically displays abstract trajectories of viewers’ train usage history as they place their IC travel card, such as Suica or PASMO, over the terminal. They can enjoy looking back at their past activities or guessing the activities of their friends who experience this work together. This work produces a different display depending on the daily activities of the participants. “Sharelog” can also be said to be a new-age work of "Public Art" since it is based on the use of the everyday IC card.
