If you don't want another device to lug around and/or don't want to pay $350 for it, you may consider Panorama360 which does essentially the same thing. It is an iPhone app that creates a 360 degree panorama that is both virtual and interactive. However, unlike the Rikoh Theta S, it is necessary to slowly film around the center point to capture everything in the 360 field of vision. It won't be a perfect rendering but will capture more than enough.  The images will reside on your phone, or you can login to the website. Nonetheless, for free you to can take pictures of amazing places and have a full perspective. Once again, you are now on the inside looking out.
