Patent ID: 7647716

Claim:
A point of sale display comprising: a liquid motion lamp comprising: a lamp base portion; a clear container extending vertically upward from the lamp base portion; a first lamp material residing in the container, the first lamp material being in a solid phase at room temperature and in a liquid phase at a higher temperature; a second lamp material residing in the container and adapted to cooperate with the first lamp material, which second material is in a liquid phase at room temperature has a lesser density than the first lamp material at room temperature, and a greater density than the first lamp material at the higher second temperature; a top piece residing on top of the container; and a light and heat source residing in the lamp base portion cooperating thermally with the first and second lamp materials to heat the first and second lamp materials, wherein heating the lamp materials causes a portion of the first lamp material residing proximal to the lamp base portion to agglomerate and form globules which rise within the second lamp material and to cool proximal to the top piece and fall within the second lamp material back to the lamp base portion resulting in an ever-changing display of shapes and motion within the container; second heat source wherein the light and heat source provides light and heat to the container and the second heat source provides heat only to the container; a temperature sensor measuring a temperature of the liquid motion lamp for providing temperature measurements; an electrical circuit electrically connected to the temperature sensor and to the light and heat source for controlling power provided to the light and heat source; at least one shelf residing proximal to the liquid motion lamp and positioned between a shoppers area and the liquid motion lamp whereby the ever-changing motion of the lamp materials within the container attracts and retains the attention of shoppers; and products residing on the at least one shelf wherein the ever-changing motion of the lamp materials within the liquid motion lamp draws attention of shoppers to the products.
