There are millions of ways to generate ideas to come up with new concepts for your projects. You can use your subconscious to come up with an idea or you can consult the Idea Generator for random associations. This tool is great because it gives you combinations of terms that are usually unrelated, but your mind will still try and connect them. This exercise will create lines of thoughts that can be completely novel.
Add to the three generated words some keywords from your own project and you get an endless list of inspirational sentences. Most of them will be non-sense, but they may still give you a seed for an idea. Of course you can simply use a dictionary for this purpose, but this tool is more convenient.
