About the Prototype black outline icon
A smartphone seen front-on holds a wireframe cube built from edges and small round vertex nodes, wrapped by two curved arrows that suggest it is being rotated and tested. The pairing reads as an early working model, a mockup under iteration. Use it for product development pages, app prototyping tools, 3D modeling software, design-process slides and innovation or R&D sections.
The cube sits centered and tilted so all three faces read at once, while the broken arrow ring leaves clear space at the corners. The phone frame is kept plain, with only a speaker slot and a home bar, so the model stays the focus. Works well beside development, testing and innovation icons at 48px or larger.
This is the black outline version of the prototype icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
