Hidden Messages

i think this is link is useful

Weiß & Spicher logo is an example that I have designed for a wood workshop team of2 partners, a carpenter and a painter, it's message you can tell by looking at the design, that this is a workshop and they do cut and paint on wood.

1. London Symphony Orchestra

Designed by The Partners, the London Symphony Orchestra logo is in its entirety a marvelous example of hidden meaning in logo design. Most likely the first thing you’ll notice in this logo are the letters LSO, an acronym for the name of the company, but with an extra effort you’ll also be able to visualize an orchestra conductor holding a baton in his hand. This seems to me one of the best examples of hidden meaning, first because is hidden in plain sight, but more importantly, because the secondary element—the conductor—has a very strong conceptual connection with the essence of the business; which makes this logo very special.

2. EIGHT

This logo was made by Stylo Design, a design agency from Covent Garden, London. The entire logo is created with only one number; the number8. By omitting certain parts of this number, they were able to create the brand name.

3. MERCK Pharmaceuticals

The pharmaceutical company's logo is made up of a capsule and two pills. In a very scientific poll of the two people next to me,50% were surprised, while the other50% said that's the only thing that logo could possibly be.

4. CLUENATIC

This was a logo created for a puzzle game called Cluenatic. This game involves unraveling four clues. The logo has the letters C, L, U and E arranged as a maze. and from a distance, the logo looks like a key.

5. Elettro Domestici Home Appliances

The designer of ED Logo – “Elettro Domestici -Home Appliances” in English, changed the concept of traditional logo designing through this logo. The designer has amazingly used the negative space to demonstrate the letter “E” and “D” making the logo look like an electric plug.

6. XNA

This collection of tools used by video game developers has a clever logo. The orange portion of the “X” actually represents the letters “XNA” in morse code.

7. Rehabilitation Hospital Corporation of America

This logo communicates so much with such a simple design. The company’s tag line is “We rebuild lives, step by step by step.”

8. PICASA

The colorful portion of Google’s Picasa logo represents a camera shutter while the negative space is a house. Casa means “house” in Spanish and Pi can be short for “pixel index”. If you put them together you have a house for your pictures.

9. Eighty Twenty

If you spotted the hidden symbolism you have earned yourself +2 geek points. The squares above the ‘Eighty20′ when read in binary (1010000 &0010100) form the numbers80 &20 respectively.

The one I dig the most is of Cisco

It is a multinational networking equipment company and clearly the blue lines represent electromagnetic spectrum, but the hidden message has a story. Cisco was founded in San Francisco in Usa and the blue lines resembles exactly the famous Golden Gate Bridge of San Francisco.
