I have recently come across the work of artist Sandra Carvajal (www.sanstarling.com) and my attention was caught by a couple of triptychs, with videos demonstrating how the three elements in each are interchangeable. This enables the viewer to move the elements around to create a new painting and decide which configuration they find the most pleasing.
Perhaps because the images seem to echo leaves and stones respectively, the words of Charles Wesley's hymn sprang to mind.
Finish then, Thy new creation; pure and spotless let us be; let us see Thy great salvation perfectly restored in Thee. (Charles Wesley)
A reflective exercise could be for a viewer to reconfigure a triptych to their satisfaction, while also pondering the changes to personal life/society/creation that might be most pleasing to God.
I am challenged to create a similar triptych (I discover this is no easy task!) with an image more obviously related to creation. Watch this space!
