Here is a simple and elegant idea I have been toying with. It is a golden rectangle with a fibonacci multispiral centered in its largest square. The styling, font, etc depend on what your company's business is (I used a console style font assuming you deal with computers). If you want to send me some info or talk about more logos:

It's not really your logo if you copy it from somewhere else.

That would be like calling every photo of a horse plagiarism of the first photo ever of a horse.
But I understand your point, claiming credit for a particular graphic would be unfair.
Credit for the multispiral goes to:
