playful / theme
A whimsy of line and shape, a childlike frolicking, drawing gleefully outside the lines. The playful is merry and frivolous, enjoyment for the pure pleasure of the thing itself, without ulterior motive. The playful is indifferent to strict structure -- although it is by no means bereft of order. Rather, it does what it will within its world -- happily, more or less obliviously, certainly with delight.
