An openable structure, such as a greeting card or book, with a body, a cam lift mechanism, and at least one decorative element fixed to tab portions of the cam lift mechanism extending through cam slots in the body. The cam lift mechanism is actuatable by pivoting subpanels of the body away from each other. Pivoting of one of the subpanels causes lateral movement of a cam lever, which then pulls an extended arm portion of a rotating portion of the cam lift mechanism, causing the rotating portion to rotate about a primary axle. The cam slots guide the decorative elements radially outward or radially inward toward the primary axle upon rotation of the cam lift mechanism, causing the decorative elements to pop up or extend outward from the body.
