interchangeable with each other to allow device 10 to be configured in a variety of arrangements for example fig3 illustrates one alternative arrangement and is referred to by reference numeral 10 39 as shown in fig1 each of the segments 12 18 are coupled in an end to end manner further the segments are rotatable relative to each other as illustrated by the arrows to increase the number of possible arrangements as shown in fig2 a 2c segments 12 18 each have a ball 26 on one end and a socket 28 on an opposite end in this way the segments may be removably coupled to each other by forcing one of the balls into a socket of another segment the friction between a mating ball and socket will preferably be sufficient to allow two connected segments to remain in a given orientation relative to each other until grasped and rotated by a user exemplary materials for constructing the segments include woods plastics composites metals and the like disposed within and extending from balls 26 of segments 12 18 is a writing mechanism 30 such as a ballpoint pen in this way regardless of how the pieces are interconnected at least one writing mechanism will be able to producing a visual image as illustrated in fig1 it will be appreciated that not all of the segments need to include a writing mechanism for example segment 20 is an end segment and does not include a pen although one could be provided further segment 20 conveniently includes a pair of arms 32 34 to which segments 22 24 respectively are coupled in this way various other segments may be coupled to segments 22 and 24.
