The intricate motion, pleasant responsiveness, and luminous color of the Sandboxes are designed to fascinate and appeal to the senses. Interaction is tactile, experienced through the soft touch of a finger, making the experience feel more personal. Sandboxes are quiet. They require little conscious attention. Sandboxes are intended to free the unconscious and stimulate what may lay unattended within.

Sandboxes are direct, simple enough for a child, and rewarding, regardless as to cultural or technical background. They require no formal language. The metaphor of sand transcends boundary. The Sandbox Project is equally accessible in New York, New Delhi, or New Guinea.

The design of the Sandboxes emphasizes simplicity, balance, and harmony. They are constructed with natural materials and finishes that are a pleasure to touch. Their overall shape and construction is intended to suggest an ordinary playground Sandbox.
