I use visuals in my Vision Architecture workshop and templates I've created to help folks during their brainstorming phases so they feel comfortable with the various steps we take to go from what just seems like a snapshot of an idea into real, functional, solutions for life, products, emergencies - whatever you're looking to create.
Here are some lightbulb maps to use during our workshops for notes and brainstorming. These are not high resolution like the ones we use in the workshops, fyi.
