"at <case sandbox>" is an interactive work using i-trace system*.
Footprints of various animals (e.g. cat, lizard, rabbit and elephant) follow users who step into the desert image projected onto the floor.
When someone crosses the other's footprints, people in the environment can catch a glimpse of the animalﾕs habitat such as sea, meadow, flower garden, etc., as if the crossing evokes
each animal's memories. Imagine the presence of animals from those footprints and scenes.

Animal tracking is a skill to read animal's footprints left in the nature. Tracking tells so much information (such as species, size, sex, territory and habit) which makes it possible to
characterize the animals vividly.

A footprint itself exists in the place but also tells the existence of someone there sometime ago. ("at" is a word not only for a point in the space but also for a moment in the time.)

* I-trace is an interactive system for illuminating the space developed by Yasuaki Kakehi. Using human tracking, computer graphics and projection technology, this system enables to draw one's trace and their crossing with various dynamic images in real-time.
