ABSTRACT:
A floor mat includes a rectangular base section that has oppositely spaced edge portions and a planar top surface provided with surface indicia. The base section is formed from durable material to withstand inclement weather conditions. The floor mat further includes a plurality of thermochromic dyes for selectively displaying at least one footprint on the top surface such that the footprint automatically appears and disappears when a temperature of the top surface falls below and above a threshold temperature. A hand-operable actuator is included that has a cavity for holding a selected quantity of fluid therein. The actuator is slidably engageable with the top surface such that the top surface temperature can be regulated by the user.
