The present invention is a composite structure that changes shape as temperatures change. The composite structure utilizes a flexible substrate. The flexible substrate is static and does not change shape by itself in response to changes in temperature. A supports structure is affixed to the flexible substrate. The support structure is made from bi-layer films that change shape in response to changes in temperature. The support structures are formed into complex shapes that are smaller than the flexible substrates they support. As a result, when the support structure are affixed to the flexible substrates, the support structures cause the flexible substrates to buckle, bend and twist as the support structures change shape with temperature. The support structures can be designed so as to cause the specific changes in the flexible substrate to as to mimic the natural blooming movements of a flower petal or leaf.
