This was made as an add-on to the Wobbly Goblet Inn (since renamed as the Lucky Mudcrab), a mod by mALX. The idea was that the player could find either a piece of charcoal, or a paintbrush, that would allow the poster to be defaced, or enhanced. The poster is "animated" in the sense that the flips between states are a pair of animations that the dialog script can "play" to effect the change. I was working on a progressive animation for the painting, but never completed it.
The mod is packaged as a BAIN archive, because I use Wrye Bash. That is compatible with other mod managers, but may require some extra work. I will NOT ve re-packaging any of my mods for other managers, especialy not Nexus ones.
Note that it is dependent on the Lucky Mudcrab, as the .esp places the poster there. Anyone who uses it as a resource will be able to work with that.
