I used to do something very similar to this turn around technique. I'd put my hands up in front of my face until everything else just sort of blurred out, and then I'd think where I wanted to be and slowly take my hands down and find myself in the place I'd thought of. I only ever went to three or four place so it seemed to work well. I never had the opportunity to play around with it to see if I could go anywhere else...but I'm looking forward to trying!
