2d 3d 4d orbitals?????? eh?

i may well be answering my own question here, but anyhooos...
from an orbital where the right hand is held above the left in a verticle line (more or less) and the poi are in the process of doing an orbital ive been swapping the position of my hands so the left goes to being on top and the right is below. so far ive only managed a clean series of 4 swaps once, and that looked to me like a verticle version of an infinite airwrap that i do horiziontally going in from the corkscrew. so the question is, because i read the term 2d and 3d orbital elsewhere, is this what im doing by swapping the hands? i have no idea of what the terminology means and i just want to match what im doing up to some words so's i can understand more stuf when i read it.
peace
