I know nothing about Pattern Matters and currently have an email into them to find out more info. From the look of their recently updated portfolio they are making some genuinely beautiful paper and typographic products from calendars to the stunning 3D posters you see here. Looking at the process photos the attention to detail exhibited here is simply mind-blowing.
Update: This is the work of Lim Siang Ching, a graphic design student in Singapore who is graduating from LASALLE College of the Arts. These are her degree projects.
