2x2 grid of four panels. Each panel is a large 3D glyph [A] built as a typographic sculpture made from objects of a specific era/invention; chaotic but legible assemblage, realistic scale of constituent parts, strong contact and occlusion between stacked items; rich textures (plastic, metal, rust, wood). Themes for the four panels: [Эрин хослол]. Clean isolated background. Three-point studio lighting with a softbox overhead. Isometric or front-facing Cinema 4D render, ambient occlusion, 8k, Adobe Substance materials. Avoid illegible shapes, flat 2D fonts, handwriting, paper textures, messy backgrounds, or floating objects.
