This shirt design was created using the open source software Processing. I used Processing to collect the data of this database, which contains the magnitude of the largest earthquakes in Japan over the last 33 years.
This data was used to create a visually pleasing composition using the national Japanese flag as center piece, with bits of concentric circles representing the magnitude of the respective earthquakes.
The shirt was sold via the T-shirt company Teeville. All profit went to the the victims of the Quake.
