I designed the wave logo shown here for my web site which now resides at http://ray.tomes.biz and is mainly about cycles and the harmonics theory with some other random stuff such as some art and champagne wire sculpture.
Unless I tell about the design, no-one will every know...
The three waves in red, green and blue are in the exact proportion of 3:4:5 in frequency. These frequencies are the correct relative frequencies for the three colours shown. Also, they are the frequencies of a major chord in music such as G-E-C. Lastly, 3:4:5 are the proportions of the famous right angled triangle of pythagoras who was also the founder of the mathematical basis of music and harmonics.
