I also created my own icon, hehehe.

I don't know what is the point in bashing other's people work without having a clue about what you are talking about.
The design you are talking about exists since the first hard disks appeared and you can find them in scientific publications dating waaaay back anything you know. It represents the different platters that composed (still used nowadays) a hard drive.
The idea of using this design for datacoin was both accurate and nice.
