I am engineer working on field of Petroleum terminal in Thailand with experience more than 20 years. I interest & wonder about number e.g. fibonacci link to golden section ratio and link to many life forms.I got to know Sloan'sequence, when I search Mathworld and found fibonacci link to Resistor network. But when I read Alex adventure in number land, I want to listen sound of Recaman sequence. After listening many sequences, I try to create sequence which easy concept like Receman. I found new one which when play at fast tempo and over drived guitar, it sound like heavy metal music.
