This poster has been designed to promote a conference on Visual Sociology. The choice of the Teletubbies was not accidental: it is one of the research topics of the invited researcher. However, Teletubbies pictures are very poor quality! Therefore, I used a hack to produce a high-quality print poster: I enlarged the picture, and then I applied a pixel mosaic filter. Thus creating a new image in 300dpi full resolution, suitable for printing.
