Aval describes the medium as "brushed aluminium" and the works may be seen as a contermporary form of "Op Art". Given that many of the pieces are colourful, it would appear that painthas also been employed to achieve the artist's vision. This style has been called "Grind Art", which alludes to the textures and designs applied to the metal's surface. Rather like a huge etching plate, where the plate itself, not the print, is the artwork. The multiple linear patterns catch and reflect light and the work would no doubt shimmer according the the movement of the viewer's position.
