David K Butler: Here is a full set of iceberg diagrams. The score is how many full squares there are, counting the ones above the waterline as positive and the ones below the waterline as negative. Given a list of integers (eg 8, 6, 0, -5, -8) can you make an iceberg that will produce exactly that list? #MathSky
