It’s hard to beat cleverly used negative space while designing logos as can be seen in the following logos.
FedEx
The FedEx logo is notable for containing a hidden right-pointing arrow in the negative space between the ‘E’ and the ‘X’. This arrow in the FedEx logo has been used as a form of subliminal advertising of the brand, symbolizing forward movement and thinking.
The WWF logo has an immensely appealing and positive image, which is seen as caring, responsible and credible.
In 1956 an abstraction of an eleven-feathered peacock was created to indicate richness in color. In 1986, the peacock's head was flipped to the right to suggest it was looking forward, not back. The eleven feathers from was shortened to six to reference NBC's six divisions: News, Sports, Entertainment, Stations, Network and Productions.
Microsoft's ingenious "Mouse" Logo shows a mouse sneaking beneath.
Apart from showing the two B’s it also resembles the blackberry fruit!
The BigTen logo from the U.S. college football league is an example of problem solving using negative space. In the early 1990s the BigTen league expanded from 10 to 11 instead of changing the name, a numerical eleven was carved out of the text.
A brilliant solution. The problem now is that the league is thinking about expanding to 12 or 14 members. A brilliant solution to repeat?
And a couple more -
