Here's a short vid of the Sandcrawler Mod Players. For ease of installation a new Animations pack and Texture pack was made. If we can keep it this way then all we'll need is a simple switching application for the properties file to go from Mod version to Regular version before each boots up.

Sorry arramus, I don't think the videos work, it takes too long to load if it loads at all.
Maybe you caught it at a bad time. It downloads very quickly for me.
