The coming together of the real and the virtual in everyday life is where the technology is headed at. One of the latest Open Source project from Google is the Interactive Spaces.
The image above shows blob tracking. Men are blobs and the floor makes colored circles appear underneath the feet of the person and follows him around. Interactive Spaces also provides activities’ runtime environment. So, you can use just one web app to deploy, start or stop the activities running on multiple computers on your local network. You might want to get hands-on with it, so check the project details here.
