Here are a few pictures I took a while back showing the magic loop style of sock knitting.
Starting a row
Row in process
as you are knitting you will be working on the two needle tips and the cord from the needle will be on both sides of your hands with the row you are working on to the front of the needles and the other part of the row will be resting on the cord to the back of where you are working.
Knitting the row
and this whole thing probably doesn't make any sense....but I try.
