At a time when visual arts seem to have exhausted much of the traditional resources, artists dare with new techniques and methods to enter an unknown soil where everything is possible. Thus, there is room for surprise, innovation and exploration, in a novel and, at times, risky forms of expression.

One of these examples is the resource to X-rays to capture images. The use of radiographs in art is not entirely new, although its applications have been mostly for study purposes, to discover the invisible layers of paintings, analyse pieces in authentication processes or look for hidden brush-strokes of the great masters, with the will to better understand their creative process. The use of this technique for genuine artworks, however, is quite recent, but its appeal is such that some artists have specialised in imitating the aspect of an X-ray in their proposals, as so the Londoner Shock-1 does.

Beyond the curiosity of analysing objects from their deepest layers, the truth is that its visual impact allows getting unexpected results, with an undeniable artistic potential. This is the path that some creators have followed, in which some have ended only by chance or derived from a professional speciality that is in direct contact with this technique. For this reason, many authors of radiographic art are scientists or doctors who have known to see in their daily images a different creative application. We share some of their proposals with you.

Photographer Nick Veasey explores a more human and active side in his proposals. The use of X-rays for this author has a more analytical and less compositional aim. As he himself explains, his work tries to transcend what’s visible in a world dominated by the image. This way, all the connotations that we associate with an ideal appearance of wealth, power or status dissipate. He aspires to look for what is beyond, in the essence of what makes us equal, while revealing hidden details about structure, form or movement. His photographs are fascinating and captivating.

Arie Van’t Riet, L: “Art, flowers” - R: “Sandersonia Dragonfly Butterfly”

Arie Van't Riet is a medical physicist who ended up making art through X-rays. In his interior studio, provided with three X-ray machines, he composes his floral still lifes, in which the elegant delicacy of the petals, the transparency of the leaves or the fragile structure of the butterfly wings are always visible. The of Van't Riet combines this work with a digital colouring task, to give rise to these images full of harmony and balance.

Steven N. Meyers, L: “Celosias” - R: “Red Magnolia”

Steven N. Meyers moves in a similar way, although this author dismisses digital colouring in his compositions. In that sense, his work is more naturalistic and offers results closer to traditional screen printing or lithography. But what he also shares is the search for balance in the image. His choices are never left to chance. There is a serene elegance based on the structure, the staging of the elements and the purity of the light. Therefore, the whole of his work manages to convey a great hidden beauty.

The circle as critical device and the marker as contemporary catalyst

POSCA, the Japanese brand of water-based paint markers, has established itself since the 1980s as a central instrument within contemporary artistic practices associated with urban art, illustration, graphic design, and interdisciplinary experimentation. Its opaque, highly pigmented, fast-drying formula—compatible with surfaces as diverse as paper, wood, metal, glass, and textiles—has enabled a technical expansion that extends beyond the traditional studio, engaging public space, objects, and installation practices alike.

In this context, POSCA operates as more than a working tool; it functions as a material infrastructure for contemporary creation. It is a technical device that enables immediacy of gesture without sacrificing chromatic density or formal precision. Its versatility has contributed to the democratization of languages historically associated with painting, fostering a more horizontal circulation between professional and amateur practices.

This expanded dimension of the medium finds a particularly compelling conceptual framework in The Rolling Collection, a traveling exhibition curated by ADDA Gallery. The project proposes a collective investigation of the circular format, understood not merely as a formal container but as a symbolic structure and a field of spatial tension.

Historically, the circle has operated as a figure of totality, continuity, and return. Within the framework of The Rolling Collection, the circular format shifts away from its classical symbolic charge toward an experimental dimension, becoming a support that challenges the hegemonic rectangular frontality of the Western pictorial tradition. The absence of angles demands a reconsideration of composition, balance, and directional flow.

Rather than functioning as a simple formal constraint, this condition generates a specific economy of visual decisions. The curved edge intensifies the relationship between center and periphery, dissolves internal hierarchies, and activates both centrifugal and centripetal dynamics. The resulting body of work interrogates the very processes through which images are constructed.

Following its 2025 tour through Barcelona, Ibiza, Paris, London, and Tokyo, a selection of the exhibition is presented at Art Madrid, reinforcing its international scope and its adaptability to diverse cultural contexts. The proposal for Art Madrid’26 brings together artists whose practices unfold at the intersection of urban art, contemporary illustration, and hybrid methodologies: Honet, Yu Maeda, Nicolas Villamizar, Fafi, Yoshi, and Cachetejack.

While their visual languages vary—ranging from graphic and narrative approaches to chromatic explorations charged with gestural intensity—the curatorial framework establishes a shared axis: a free, experimental, and distinctly color-driven attitude. In this sense, color functions as a conceptual structure that articulates the works while simultaneously connecting them to the specific materiality of POSCA.

The marker’s inherent chromatic vibrancy engages in dialogue with the formal assertiveness of the circle, generating surfaces in which saturation and contrast take center stage. The tool thus becomes embedded within the exhibition discourse, operating as a coherent extension of the participating artists’ aesthetic vocabularies.

One of the project’s most significant dimensions is the active incorporation of the public. Within the exhibition space—activated by POSCA during Art Madrid’26—visitors will be invited to intervene on circular supports installed on the wall using POSCA markers, thereby symbolically integrating themselves into The Rolling Collection during its presentation in Madrid.

This strategy introduces a relational dimension that destabilizes the notion of the closed artwork. Authorship becomes decentralized, and the exhibition space transforms into a dynamic surface for the accumulation of gestures. From a theoretical standpoint, the project may be understood as aligning with participatory practices that, without compromising formal coherence, open the artistic dispositif to contingency and multiplicity.

The selection of POSCA as the instrument for this collective intervention is deliberate. Its ease of use, line control, and compatibility with multiple surfaces ensure an accessible experience without diminishing the visual potency of the outcome. In this way, the marker operates as a mediator between professional practice and spontaneous experimentation, dissolving technical hierarchies.

The title itself, The Rolling Collection, suggests a collection in motion—unfixed to a single space or definitive configuration. Its itinerant nature, combined with the incorporation of local interventions, transforms the project into an organism in continuous evolution. Within this framework, POSCA positions itself as a material catalyst for a transnational creative community. Long associated with urban scenes and emerging practices, the brand reinforces its identity as an ally of open, experimental, and collaborative processes.

POSCA x The Rolling Collection should not be understood merely as a collaboration between a company and a curatorial initiative; rather, it constitutes a strategic convergence of tool, discourse, and community. The project proposes a reflection on format, the global circulation of contemporary art, and the expansion of authorship, while POSCA provides the technical infrastructure that makes both individual works and collective experience possible.
