Talk:OLPC Human Interface Guidelines/The Sugar Interface/Layout Guidelines
There's a small inconistency in the definition of the grid size.
"The system functions like a basic floorplan which allows interface elements to tile neatly within its boundaries. The grid consists of a 12x16 array of square tiles."
However, the image shows:
"Screen Grid (16x12 grid cells)"
Traditionally, grid coordinates are shown ( width x height ), so an inconsitent application here may confuse a designer trying to design for the system without reviewing the image for aspect reference.
