ABSTRACT:
A three-dimensional ornamental device adapted for rotation about an axis to produce a changing perspective that creates an interesting visual effect can be made by a process including the steps of cutting a sheet of material into a desired geometric shape, making cuts into the sheet material to form a series of disconnected adjacent strips, and bending the strips from a reference plane so that the strips are angularly spaced apart from each other.
