In this paper I create planar images using lists of pairs of orthogonal ellipses with a common center (POEs) as the single graphic element. Changing attributes of the POEs such as size, color, position, rotational orientation, and excentricity using linear and trigonometric functions gives rise to a wide spectrum of images. Some combinations of parameters appear to produce abstractions of three-dimensional organic creatures and of phantastic assemblages that might have come out of the Burgess Shale in Alberta, Canada.
