Diagonal grid pattern mat

The image depicts a rectangular mat composed of small, square, blue tiles arranged diagonally. Each tile possesses a slightly raised edge, creating a grid-like pattern across the mat's surface. The uniform spacing and consistent blue hue of the tiles contribute to a regular, tessellated appearance. The raised edges introduce a three-dimensional quality, giving the impression of individual tiles. The mat's function appears to be providing a textured or patterned surface.
