360 degree images and video are incredibly easy to create and share, with the right tools. The latest 360 camera from Ricoh is the Theta V. The camera can capture both images and video. It can be controlled remotely from an iPhone and instantly transfer images and video. With the right wordpressplugin, you can post images or create your own virtual tour of any site.
For higher quality images you can upgrade your gear to any DSLR camera with a fisheye lens and a special gimbal, though this adds work on the back end as the images need to be stiched together. Google has a growing collection of virtual tours in their Street View app available here.
