I saw this article about a new PC interface: http://www.grimrock.net/2011/08/23/new- ... interface/

However, the article doesn't say anything about where to get it, so I assumed it was just a teaser. I have since found a video of someone using this interface here: https://www.youtube.com/watch?v=5rIFo7f ... redirect=1

So where can I find this?

Those are OLD, it was just an early interface, long since improved into the current version
