We present a prototype for a tangible user interface, designed for interactive data visualization, which we believe will be useful to facilitate collaborative work in data analysis. Our hybrid system combines a desktop-friendly user interface with a two-dimensional display screen. Users interrogate the data by manipulating 'tokens' on the table and screen, which display the results of the user's query. We demo our system with UN demographic data, but we've designed it so that the user can enter their own data to view it.
