An artistic diorama in Sélestat, France, depicts a stylized desert or alien landscape under artificial sunset illumination

An artistic diorama in Sélestat, France, depicts a stylized desert or alien landscape under artificial sunset illumination. The scene is contained within a dark-framed enclosure. The base layer consists of fine-grained, orange-red material resembling sand. Layered, undulating cutouts, colored in muted orange and reddish-brown, form a mountainous or dune-like topography in the midground and background. A circular, intense orange light projects onto the upper rear wall, simulating a setting sun. Below this, another smaller, circular red light illuminates a section of the middle ground. Four translucent, sculpted objects, resembling jellyfish or bioluminescent flora, are suspended from the top of the enclosure by thin lines. The leftmost object is white, multi-lobed, with dark, wire-like tendrils extending downwards, casting a prominent, elongated shadow onto the back wall. Two central objects include a yellowish, single-lobed form and another white, multi-lobed form with tendrils, both illuminated by warm light and casting shadows. The rightmost suspended object is a white, single-lobed form. Some of these objects appear to be attached to flexible stems containing small embedded lights, creating glowing points. On the front right, a black, cylindrical projector device with a blue band is mounted vertically on a dark base, pointing into the scene, likely responsible for some of the projected light effects. The overall lighting creates strong contrasts and elongated shadows, enhancing the depth and otherworldly aesthetic. No people are present.
