I’ve made several versions of a fish mobile celebrating Gerard Manley Hopkins’s poem. This is the most ambitious. It has echoes for me of Escher’s metamorphoses. I’ve made the birds loosely based on the finches he refers to. Like the other fish mobiles it undulates gently even in slight air currents.

Glory be to God for dappled things – 
   For skies of couple-colour as a brinded cow; 
      For rose-moles all in stipple upon trout that swim; 
Fresh-firecoal chestnut-falls; finches’ wings; 
   Landscape plotted and pieced – fold, fallow, and plough; 
      And áll trádes, their gear and tackle and trim. 

All things counter, original, spare, strange; 
   Whatever is fickle, freckled (who knows how?) 
      With swift, slow; sweet, sour; adazzle, dim; 
He fathers-forth whose beauty is past change: 
                                Praise him.
