One great way to come up with more creative ideas is combine things in new ways. Often, the more random or unrelated the things combined, the more creative the idea seems to be. But in the eyes of the creator, those things probably aren't so random or unrelated after all. Where most people see randomness, the creator spots a clear connection, a unifying link.
Unifying links can be found between pretty much everything, if you look deep enough. Visuals can make those links much more obvious than words alone. Try it out with the ten things pictured in the image above: Apple, airplane, airstream, art, arrows, almonds, apricot, automobile, avenue, atmosphere. Need a hint? The answer is in the picture - four times!
