Building on the work series of Belitung VR, this article seeks to explore a narrative framework for digital cultural heritage storytelling. Belitung VR is a serious game to disseminate Belitung-related cultural knowledge in VR, where users can freely explore in the reconstructed Arab dhow shipping between China and West Asia to collect clues to the causes of the wreck. The proposed framework consists of narrative goals (the physical and meta-physical), narrative elements (character, world and plot), and narrative grammar (immersion, interaction, rhetoric and factuality). This work can serve as a practice guide and evaluative framework for designers/artists with an aspiration to digitally disseminate cultural heritage.

The imagery is conceptually reformulated as his practice evolves through experiments with new ways of working. Leonardo readers will no doubt appreciate the shot of Acevedo’s image titled Skull v2 on the cover of the journal (Volume 34, Number 4, 2001). His 4D Memory Cluster was reproduced on the back cover of the same issue. The three main periods that define Acevedo’s evolution are presented chronologically in the volume. From 1977 to 1987, his analog period, he used traditional media, painting, drawing, and film. The digital period extends from 1983 through 2007. Because this work was mathematical and included a focus on symmetrical operations, it gave him a perfect foundation for the digital environment. Indeed, his work dramatically demonstrates an artmaking approach that was a particularly good fit since his style meshed conceptually with the supporting language of digital tools—regardless of whether his goals were twoor three-dimensional. The new technologies additionally aided him in creating visually overlapping sequences or merging coexisting levels of reality, two of his recurring themes. Also emblematic of his vision is imagery that has a metaphysical bent, sometimes expressed with geometrical abstraction and sometimes with figuration. In 2007 Acevedo shifted into an Electronic Visual Music (EVM) period, a term he coined in 2013. These pieces include a synesthetic element as well as computer animation. The synesthesia discussion of the EVM period reminded me that the recent focus on genetic synesthesia has made it easy to lose sight of artwork that aims to compel audiences to engage on multiple sensory levels. Acevedo deals with synesthesia phenomenologically, integrating realtime video-mix workflows into his audiovisual studio practice. Of the four essays, I found art critic Peter Frank’s the most informative, succinctly capturing Acevedo’s evolution from a pioneer of desktop computer art in the early 1980s to his music videos period. According to Frank, Acevedo sets computergenerated structures and manipulated images in motion, one morphing into the next in response to sound composed by and large by collaborators. This insight points to the one downside of this book: electronic jazz collaborations resist printed publication. Since Acevedo began as an analog artist, I was particularly fascinated by the way his digital video and digital print work resonate with his roots in painting, which appears to remain at the core of his practice conceptually. Since his career began, he has shown his work in over 135 group and solo art exhibitions in the U.S. and internationally. He also has fruitfully collaborated over the years.

in a thriller or whodunit setting; it is the scientists who trap themselves in a labyrinth of chaos as well as order, leading to death and madness but also to beauty and deep human feeling. No less important than the intelligent mix of science and fiction is the use of the comics medium. A translation from the French (first edition: 2019), this book maintains the typical French hardcover album format, distinguishing itself from the nowcommonplace trade novel format of nonfiction comics work. The style of the art is radically anti-mimetic, another feature that sets it apart from most nonfiction works on science and scientists in the comics field. The Phantom Scientist does not attempt to faithfully document or illustrate the idea of science in action, as Bruno Latour put it. The characters and the settings are drawn in highly stylized and decidedly cartoonish ways, closer to Garfield than to Watchmen, for example. The background is equally schematic, sometimes reduced to one single color field, while the structure of the building and the park hosting the research institute look more symbolic than real. Yet this schematic way of drawing perfectly matches both the layout and the narrative techniques of the book, which establish a strong dialogue between the page’s grid and the hard-edged visual representation of people and objects. The use of colors, finally, is that of an extreme clear line style, with sharp contour lines and no chromatic variations within each contoured section. These seamless echoes between lines, forms, and colors continue in the elementary yet efficient montage and linear storytelling techniques, which shy away from any form of temporal disruption to slowly build a tight network of correspondences. The Phantom Scientist is not a puzzle but a journey, one with an open end where each new step helps thicken the plot, allowing for countless rereadings. Even if the story unfolds in a linear way, many gaps remain. As one of the scientists confesses near the end: I can speak about the “how” but not about the “why.” The work wins in both ways, however. It is a wonderful introduction to the stakes and challenges of modern science. It also discloses the no-less-mysterious questions that link machines and algorithmic thinking to what we can continue to call the human factor.

What Tschudi certainly has done is use Piranesi as a foil to delineate a history of modernism, particularly architecture. As Tschudi clearly states, this book contains only a small and select presentation of Piranesi’s prolific output—mainly his etchings, his greatest legacy. “In short, rather than a study of a historical figure, this is a book about an ahistorical Piranesi—a character reinvented in the modern age to legitimize that age precisely as modern” (p. 18, my emphasis). That Tschudi is fully aware of the precariousness of his investigation into the enigmatic nature of Piranesi is evident from this passage: “This book admittedly offers an ambiguous conclusion to the story it tells. Still, in its ambiguity, I hope this monograph may be inscribed into an esteemed genealogy of Piranesi emulations, for nothing can be more noble in this tradition than the ambition to rein in the endless and contain the infinite, only to be deceived by the format” (p. 231). I believe this book is an important addition to the literature on modernism and, of course, a wonderful exposé of Piranesi and his work. Perhaps unintentionally the book is equally important as a case study in postmodern deconstruction, authorial intent, and how the fads and trends of different epochs change dramatically our appreciation and understanding of art. This book requires close reading, keeping the ambiguities and enigmatic nature of the whole enterprise in mind.
