Poetic Expressions in Dimensions seeks to create and strengthen bonds – bonds between people and spiritual beings, bonds between people and people, bonds that express vital connections.

By creating poetic expressions that can be displayed in both two-dimensional and three-dimensional continuous form, I want my poem to illustrate how these bonds can be mutually reinforcing. I also want my poem to display how many of these bonds can be without end, outlasting the life or lives of those who are expressed in them. When expressed in three dimensions, my poem offers a navigable digital virtual space.

Each line of this poem can be extended by a repetition of groups of words in order to occupy the space provided to it, while maintaining the underlying force of those words. Each line of this poem can be enlarged by an increase in the provided size or shape, which can enable an increase in the repeated poetic message.

Potential shapes are:

•	Two-dimensional rotating and non-rotating circles of various sizes.
•	Three-dimensional rotating and non-rotating circles of various sizes  
        in digital virtual space.
•	A Möbius strip of various sizes without a defined inside or outside.

An accompanying website illustrates the poetic lines in two-dimensional space and three-dimensional digital virtual space. It can be found at Expressions-in-Dimensions.com.

A few lines of the poem will prompt my reader to insert a name or two of their own. Even though this type of prompt is most often associated with the creation of comic expressions, I have included it here to give my reader an opportunity for earnest input. The length of the underscore in the prompt does not determine the length of insert. The length will be determined by the reader. I will point out to my reader that a proper noun, a gerund, or a noun that functions as both a subject and a predicate are the best candidates for insertion.

I am gratified that my poem works in any language and hope that my reader will agree with me that the bonds and love expressed are universal.
