Neon Cyberpunk 3D Voxel Retro App Icon Set

Full prompt

A set of 9 distinct, non-repeating 3D voxel art mobile application icons organized in a precise 3x3 flat grid layout, front orthographic perspective. The collection showcases nine retro-tech objects: a 3.5-inch floppy disk, a glowing pixel heart, a vintage cassette tape, a retro gamepad controller, a magical potion flask, a pixel treasure chest, a faceted voxel diamond, a glowing high-charge battery, and a retro robot head. Each miniature item rests on a uniform frosted translucent rounded-square squircle base with glassmorphism shading. Combining neon cyberpunk hues with clean minimalism, the icons float above a pitch-black background etched with subtle circuit traces under soft studio lighting, 9:16 aspect ratio.
