If this looks interesting to you, please answer a few questions to help me decide on the direction of the project going forward.
Also, just a warning - this project is not yet licensed which means I basically have not authorized any use of it. For now that means you are welcome to use it for personal use but you cannot distribute it or modify it. Hopefully I decide on a license soon.
