NuVera Online (also referred to as NuVO) is a 3D virtual world and social network service developed by Nitrous Butterfly LLC . Users of the program can interact with other users as either Patrons (free accounts) or Denizens (paid members) using virtual renditions of themselves known as avatars. To enhance their experience users can purchase user created 3D products for use in the client program such as environments, objects, furnishings, clothing and more which they can purchase with NuVera Online's virtual currency NuVO Notes. A secondary downloadable program called the NuVO Editor can be utilized by users called Developers to import 3D models or re-texture existing models which can then be sold in the online catalog provided on the website.
