Toe up socks

Last week I took a class at my LYS in Tampa, Knit and Knibble.  It taught toe up sock knitting which is good because then I can make the socks longer to cover more of my leg.  This is what is looks like so far - the next class will teach the heel.

Now all I want to learn is how to knit two socks on one circular needle which is really supposed to be the way to go.
