Rectangularity controls the setting
Of tables, the organization of paint
On canvas, and the sport of ping-pong.
Once perpendiculars have been established
Various circular forms may be introduced:
Glasses, soup bowls, loops of color
Intended to suggest our own possible
Movements through more extensive spaces,
As when we drink, or sink into imaginary
Depths of Prussian blue, or hit the ball
Approaching us on its strict trajectory.
