Twisted model

You guys are so good at this, I’m just started and can’t get this to work…

what I want to make is this: http://www.kiwiartz.co.nz/i/d/280/j227.jpg

I was thinking this wouldn’t be so hard, seeing what you guys made here…

I used the this tutorial, but it looks like crap…

Does anybody got some tips, tutorials, anything…
