**7. Final integration (including music and staging)**

Each belt is used to anchor its corresponding scene—indeed, each scene was designed so as to align the final appearance including the moving model with the esthetics of the 3D images. In principle, this means that several belts and animations could be viewed simultaneously. In practice, however, since each set of animations requires significant computing power to render in real time, we preferred to keep each presentation separate. Furthermore, the belts are worn with a white top to provide a canvas over which the 3D visuals can be overlaid.

The final integration of the 3D graphics with the physical belts are shown in **Figure 10** for the lunar belt and **Figure 11** for the solar belt. As indicated earlier, two additional scenes are under development, one involving a large space platform and the other a dynamically changing costume incorporating fractals. The 3D images are almost complete and the belt development is in its final stages. With the relaxation of lockdown restrictions currently underway, the organization of the event itself is also now possible.

A staging scenario was developed for the presentation in front of a live audience. This script included information on the timing of each segment. This was necessary also to assist in the development of the music accompaniment. At this point in the development of the event, the music has still not yet been finalized. However, we

are proceeding as we have in previous projects, which is to mash together public domain samples of music into a coherent and dynamically interesting whole [6].

The total duration of the final show is estimated to be about 40 minutes. Following an introduction, the presentation of each of the four belts cycles through the three levels of visualization (static 2D, static 3D and dynamic 3D), along with the reading of the text excerpt, and hence each belt takes about ten minutes to present. After the individual belts are presented each in turn, the four belts are presented together in a kind of finale, without the full dynamics so as to render the processing tractable and with an additional excerpt. Following the conclusion, a book signing session is expected to be announced.

Our plan is also to stream the event for virtual participants. Indeed, the book publisher is located in Boulder, Colorado, and both collaborators and other interested parties are located there. Streaming became a de facto standard with the pandemic, and we retain that here. In addition, we are developing an app which will allow the 3d scenes to be viewed independently of the belts, as a value-added product to be made available to individuals as part of the marketing of the book.
