@Sappho: I'm using the default "Phoebus" graphics pack that is provided with the Masterwork Mod (v.3) download. Lots of the extra stuff included in the Mod calls dfhack v3 processes to make them function, and I'm not sure if the ASCII tileset is recognized by it or not. Personally, I'm using "screen capture" and the "paint" program that comes with "Windows" to edit them into the graphics that have been posted so far. However, if you'd like to draw something and scan it in instead, or even do some photomanips, that's cool too. (Stick men, not so much - the game is about Twoflower's vacation and vacation memoirs rarely include stick men, know what I mean?)
So go to the link provided by fricy and follow the directions there for downloading/getting started with "v.3". (I'd suggest you choose "no" when asked to run it in full screen mode. While you can enlarge it to cover the full screen, that option makes it easier to switch back and forth from the dfhack console.)
Extract the latest save file (from the link of the same name on my first page) into the "saves" file (located at MasterworkDF v3/Dwarf Fortress/data/save), then start the game up using the external user interface (There's a picture of a dwarf with a horned helmet on it).
Actually, you may get more of an idea about this by downloading the game, starting it up then reading the "dwarf manual" tab on the upper left corner of that horny helmed interface screen. That'll let you read in detail all the stuff included in the mod, as well as more easily access the save folder.
@fricy: Lurk as you like and please also feel free to comment about or suggest stuff without needing to take a turn. If we're not having a good time, why go to all this bother in the first place?
