Lay out 100 2.5ltr cans of paint in a 10x10 grid.
Choose 100 different colours…or 2…38…whatever you like.
Surround the grid with 4 canvasses, about 3m long by 2.1m high.
Lower 100 hand grenades into the paint, and explode them simultaneously.
Once the canvasses have dried, display them in a gallery, butted up to each other to make one continuous picture.
