A brain muffin is an original concept coming from you that is a detailed epiphany. It's akin to baking a muffin in the oven. It takes time and the right ingredients, and eventually a tasty treat.

These treats are thought-provoking ideas that are fresh-baked regularly. Think of them as idea stubs that could become an idea cake. (Generally, you'll develop brain muffins into something bigger, but you don't have to.)
