About

Open Source Automation was (as far as I'm aware) software created originally by Vaughn Rupp and Brian Woodworth.

In their own words from the website:

This project has been created with the sole purpose to make home automation available to everyone. Currently there is a lot of home automation software on the market, but they are all very expensive. This makes it difficult for the average user to set up a professional home automation system without taking out a second mortgage. On top of the cost, these programs are very restrictive. Users are forced to use only the hardware that is supported and without an open extendable architecture they are at the mercy of the software company to develop new interfaces.
The Open Source Automation project overcomes these two major problems with the home automation software industry. First and foremost, OSA is free and open source. Anyone with an internet connection can download, install and get up and running without spending a dime. Even more exciting is the open extendability of OSA. Anyone can use the open source API included with OSA to develop new plugins and expand the functionality of the system. With the openness and community focused vision the development of new and exciting plug-ins is sure to push the limits of the imagination.

I used this software for several years and even wrote a few plugins, one of them to interface the Thorian devices which you can find on here under the Home Automation > Thorian section.

Below is an image of the main interface:

The software would also allow you to design screens, add your own backdrop and apply switches and sensors to the screen at your specfic locations.

With some work, you could create pretty much any design you like.
