Idea 1:
Data visualization is a common practice today, but some much more information could be conveyed through a 3d dynamic I/O data tangibilization table. It could display data in conventional ways such as 3d bar/pie charts, but it could also display it in respect of the property of the data or the question one tries to answer. E.g. texture, color, shape can all be used to represent the differentiation in data.
Idea 2: On a second thought, creating a dynamic shape-shifting chess game would be great.
