Trinity Sunday

I wonder what pictures or symbols you have seen that relate to the mystery of our belief in the Trinity ? Fron a simple shape like a triangle within a circle to Rublev's icon of three people sitting around the same table (representing their unity and sense of interrelating together ), there have been varioous attempts over the centuries to portray the Trinity... I recently came accross a very modern version of Rublev's Icon which I would like to share with you...
