This is an early prototype for a simple program simulating the workings of a planet. The two tables below represent different "layers" of the planet. The first table is the asthenosphere, or the upper layer of the planet's mantle, where magma currents drive the motion of continental plates. The little arrows show the direction in which magma is currently moving. The second table is the planet's actual surface, at first covered entirely in water. The numbers in each cell show the altitude of the rocky surface in kilometers, measured from the seafloor; altitudes of 3.5 km or more rise above the sea level. Click the "advance" button to move forward in time. For now the only events that take place are large upwells of magma from the lower mantle, which raise the altitude and change drift direction in a select region. Next features to be implemented will be continental drift, formation of trenches and mountains, and surface erosion.
