This art experiment uses repousse' technique on can metal, replicating Mayan glyphs in a wholly new context. It is somewhat time consuming to do as the technique involves impressing the individual fields into the soft aluminum metal to a gradually increasing depth.
After doing this and some other pieces involving Mayan glyphs, all I can say it that those folks must have been doing some heavy duty drugs to come up with a system of writing that involves such convoluted images!
