Columns will be added to the scene programmatically
There are, as I understand it, 2 column types - tall and short
Each column could be unique, it seems likely there will be similarities
Column Composite
Each column is composed of 5 elements
1 base image - no decal
3 decals - one for each activity state
1 mask - base and decals are animated vertically behind a static mask, this provides the illusion of a column moving vertically into, and out of, the base image
Decals are turned on and off by the user selections in the UI
