It seems a little cruel to pick flowers from habitats where they can sway in the breeze or at least swivel a bit in phototaxis and confine them to a static vase. As an offset I made this arrangement where the apparently spheroid glass vase is balance in the curved top of the ginger jar.  The dining table where they sit is always a bit wobbly, so even sitting down set these violets rocking. Of course one can deliberately set them in motion.  More power to the kinetic vase.
