A 3D world that lets users mingle in nightclubs, beaches and yachts is currently in private beta with an expected launch date of two weeks.

Created by Stable Media and the Wyndstorm Corporation, RipLounge is a free 3D world aimed at users between the ages of 25 and 40, while letting users communicate via chat, web phone and video. The two companies behind RipLounge are in the advertising business, where 25-54 is the most desired demographic.

RipLounge promises to be a 3D virtual world that users only need to create an account for and enter, rather than having to spend hours learning their way around, or crafting other alternate persona for themselves. Users will be able to interact with one another in a number of different online settings built in RipLounge, while also listening to music created by independent artists.

Readers interested in joining RipLounge can go to the Web site and enter an e-mail address to join the "VIP List." For now, it appears getting in on the VIP list doesn't appear to have any immediate benefits - it's possible users on the VIP list will receive entry to the 3D world a day or two earlier than the public.

RipLounge will be open to the public on April 1 and will make its first debut in San Francisco in mid-April. Advertising will play a role, much of it apparently being displayed from virtual overhead monitors adorning the bar and gaming areas.
