A marking paint applicator for a portable electronic locator that locates buried cables and pipes via electromagnetic emissions includes an elongated support structure and a manually moveable trigger mechanism mounted adjacent an upper end of the support structure. At least one bracket assembly is provided for removably connecting the support structure to an antenna mast of the portable locator so that the trigger mechanism will be adjacent a handle of the locator and the trigger mechanism can be squeezed by a finger of an operator's hand while grasping the handle. A receptacle is mounted to the support structure for carrying an inverted aerosol paint can and positioning a valve stem of the aerosol paint can for spraying paint onto the ground to mark the location of a buried cable or pipe. An actuating mechanism is capable of selectively deflecting the valve stem to cause the aerosol paint can to spray paint onto the ground to mark the location of a buried cable or pipe. A linkage connects the trigger mechanism to the actuating mechanism for deflecting the valve stem when the trigger mechanism is squeezed.

An mat system with each mat having sloping lips which overlap with an adjacent mat's sloping lips and are secured by interlocking joints in the mats' lips and/or by captive locking pins to form an easily assembled and interconnected flat surface. In use, opposing ledges forms a slot within holes in the top overlapping lips to receive a captive locking pin. The pin is captive by mid body prongs which fix underneath the ledges in a mat's upper lip's holes, and the pin locks and unlocks with rotary turning of the pin resulting in the pin's keeper feet fixing underneath the similar ledges in the holes of the lower lip of an adjacent mat.

Each primary element is a rotational tessellation having a plural pairs of sides extending in a generally radial direction from plural vertices, respectively. In each pair, the two sides are rotationally spaced by an angle of 60, 90, 120 or 180 degrees, and each side is substantially a rotational image of the other side. The sum of the plural vertices angles is 180, 240, 270, 300 or 360 degrees. Preferably, all of the sides are irregularly shaped, but one or more sides could be wholly or partially straight. Optionally, one or more edges of each unit are marked with indicia to facilitate matching mating sides of adjacent units. A wide variety of units may be constructed having different numbers and arrangements of primary elements. As all the units are combinations of primary elements, they readily mate with each other.

Because of the irregular side configurations, and different sizes and shapes of individual units, one can construct a continuous surface that has a natural, random and apparent custom appearance. Optionally, minor surface and edges variations are made from unit to unit to further enhance the natural appearance of the surface covering.
