Recently it occurred to me that the 2-dimensional display of skills or skill development were somewhat unnecessary. With that in mind, I developed a way to show skill growth in 3 dimensions. What I came up with was the 'skill cube'. An example of what I mean is below:

As you can see, it consists of a colourful cube. Now, the special thing about this cube is that each of its faces represent a different character's skills. In this example, I used a colour to represent each of the greek elements. Red is fire, deep blue is water, light blue or aqua is air, and green is earth. Each face is a different character (say for an RPG), and each square represents a character's skill in one particular area. Of course, it's possible to use other shapes should we desire a non-square number of skills, but in this example I use a cube for my own sanity in drawing and to keep it simple. Here we see a cube after the party has levelled up:

As you can see, certain colours are extruded. These represent increased skills. Top-face has levelled up his 'Earth' skill, while Left-face has levelled up her 'Fire' skill, and Right-face has levelled up her 'Water' skill. As experience in each area increases, these areas will extrude further. In this next example, top-face has levelled up his 'Air' skill and 'Earth' skill to an equal level, and neglected his 'Water' and 'Fire' skills, while Left-face increases her 'Fire' skill to a high level and Right-face does likewise with 'Water'.

How do you think this would work as a user interface, were the cube easily turnable and rotatable?
