Positive & Negative Seagulls in Flight Metal Wall Art, base is a piece of 2’x4′ sheet metal.  Gulls cut from sheet, make the positive images mounted via magnets, near their negative counterparts.  Gradient Grey to white shot with enamel and cleared with enamel. I mounted this with a couple inches clearance from stained plywood beneath.  Back lighting could add a nice touch and could easily be done for a nominal cost.
