Check beta video of Realaxy.

Realaxy — is a set of free online applications that allows people to find a three-dimensional model of their apartment, office or any other room, or quickly create and design it in real-time to see a photorealistic result.

Manufacturers and vendors will have an opportunity to demonstrate the three-dimensional models of household products, and users to try them in their apartments and purchase.

Note: Realaxy ActionScript Editor (RASE) changed it name and moved to new web address (I will post about it later)
