Cube Stacks and Their Views

A pile of unit cubes described by what it looks like from above, in front and from the side. Each view is a projection that keeps only the tallest cube in its line, so views constrain the pile without fixing it -- some positions are pinned down and others are still free, which is what makes counting all the possible piles a real question.
