The Modular Graphic Panels from Melt (Modern Elements Living Together) are graphics printed on square panels of wood. A range of standard prints can be purchased via the Melt website, or have a custom print made to order. I think these work best in repetition, displayed in a series as in the gallery photo shown below the jump.
The square shape of the panels lends them to repetition. The botanical prints are vivid closeups that look especially nice to me in a series.
