radial symmetry, noun, BIOLOGY:
symmetry around a central axis, as in a starfish or a tulip flower.

Digital art. I spent some time playing with the radial symmetry tool in Sketchbook Pro. I selected 16 points of radial symmetry, (for extra credit – see: forms of radial symmetry in nature) the scale ranging from 6 to 16, and got these lovely, intricate, fun flower shapes. I used a watercolor pen on a lower layer and added some color to be more cheerful and dynamic. This was just a calm and meditative thing to do — I might very well take up making these in the future, just for relaxation. I love flowers — so this was great.
