The Dutch lettering artist Job Wouters – under the pseodunym Letman – created the Rainbowgun (2009), a tool that combines multiple spraycans that can be activated at the same time. This tool allows the artist to create large-scale, multi-colored lettering. In order draw with the Rainbowgun, the maker needs involve the movement of the whole body, through which visual creation becomes a physical gesture, too.
