I love this piece by Dominic Greene for Business Insider that I have to share part of it here. Some of these I knew, some are a cool surprise. There's always a strategy behind every design - big, small or subliminal!
The FedEx logo hides an arrow in its negative space. Even a glance subliminally inspires thoughts of efficiency and forward motion.
This cool logo for Sony's computers represents the brand's integration of analog and digital technology. The 'VA' is designed as an analog waveform, the 'IO' is binary code.
This logo, introduced in 2005, cleverly uses the company's initials to advertise its number of ice cream flavors (31).
Slightly more abstract than the other examples, the Tour de France logo contains a well-integrated biker.
See the dancing bear in the mountain? The design is a tribute to the Swiss town where the chocolate was developed.
The cleverness of this logo is twofold. The arrow points from a to z, referring to all that is available on Amazon.com, and it doubles as a satisfied smile (with dimple).
