Standing ouside the Explore centre and Planetarium in Bristol, this structure is described as a signpost to the Solar System. Passers-by could use the touch screen to chose the Sun, Moon or a planet and the two arms on top of the device would point in the required direction and light up showing the current distance from Earth.
In 2006 the device was bang up to date, even indicating the newly-discovered "Tenth Planet". By the end of 2007, the Solar System had been reduced to just eight planets. The "Tenth Planet", by now known as Eris, had been refused planetary status and Pluto had been stripped of its. But the device had not been updated to reflect this.
In June 2008, it wasn't working at all.
