Titan Tupl was announced a few days back by Alexander Patrikalakis (who also announced the AWS version for dynamo). Looks like there's some docs for getting started with Titan Tupl, instructions to get it fired up on AWS, etc. I think we should consider adding it to the home page as a Graph Provider.
