In theory it has always been possible to 'edit' the minecraft graphical layout to match that of Manic Digger, but such a task would have to be done by hand, and... as a graphically minded person, such tasks can be laborious and dull to undertake. Some people have already ported over Minecraft textures to use in Manic Digger, and some of the texture's i've seen are pretty good.
Liquidhot has now made it one step easier to use the wealth of freely available user made content that exists for Minecraft... and easily tranform it into a usable Manic Digger Texture pack!
This is a GREAT opening in the availability of textures, and now every Manic Digger player can enjoy the textures they like the most!!
Almost makes my recent contest seem a little moot, but I'm very happy that this little tool has been made!
Thank you liquidhot!!
