Brainstorming black outline icon

About the Brainstorming black outline icon

A brain seen from above is split down the middle by a lightning bolt that runs from the top lobes to the base, with both hemispheres drawn as rounded lobed clusters. It stands for brainstorming, sudden ideas and mental energy, and fits workshop decks, idea board tools, innovation program pages, startup landing sections and e-learning modules.

The bolt doubles as the central fissure, so the composition stays symmetrical and reads at a glance. It pairs with lightbulb, target and puzzle icons in the same set; use it at 32 px or larger so the zigzag does not close up.

This is the black outline version of the brainstorming icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.

It downloads free as an SVG vector or transparent PNG in seven sizes, and the free online editor lets you recolor it, apply gold, silver, neon and gradient styles, add animation, or convert it to EPS, PDF and DXF.
