"Agro Box" was a piece that I created recently, intended to depict an outburst of uncontrollable anger and threat.
The box was made using plywood boards, then painted black and then scratched with a knife in places to signify a sense of anger desperate to escape. I then used the knife to scratch through the top of the box, creating a hole from which a suspended spine of wooden disks, punctured with nails is escaping upwards.
