When looking for ideas for drawing, painting, poetry or sculpture, it can be helpful to think outside the crate. Or think outside the corrugated cardboard container. Or the cube. Or the containment device. Or the little space bounded by roughly equal sides and describable by geometry.
It’s not too useful to just say “be creative,” without having some ways to encourage that in your head! Creativity is like a muscle. Once you get your mind warmed up, you will be more creative with your other projects, not just the little exercises listed here.
My mother, who is a writer as well, gave me a great idea so I’ll mention it here. She has been writing poetry and short works with five randomly selected words. That can be a great way to kickstart creativity! You can even close your eyes, open a dictionary, and point. Or find a random word generator and use that. The idea is to cause new, unexpected input to come into your mind and spark new ideas. Creativity often comes when you take two unrelated ideas and play around with how they could be connected. And it’s hard to get new ideas without new input.
Something I frequently like to do is take some object, natural or created, and examine it closely, perhaps even under a magnifying glass or microscope if you have one. Even a pinecone can be a fascinating thing to explore if you really get into examining all the shapes, shadows, ridges and texture of it. Maybe it could become part of a new creature, or an idea for a structural support on a building? This can work for artists, writers, sculptors, or anyone else who wants to get their imagination going.
Macro photography on the internet can be a fascinating way to look at the world. So can Google’s “I’m feeling lucky” feature. Take a walk and examine something you’ve never looked at before. Read an article about a subject you known nothing about. Pick a word at random and look up websites about it. Read quotes from famous people you’ve never heard of. That can trigger new ideas too.
Creativity requires imagination. If you open your eyes, literally or figuratively, and get interested in the world, great ideas follow.
