The story in New Scientist (Pulse of light creates instant origami) has a short video which nicely shows the polymer sheet folding into 3 dimensional structures.
The paper by Michael Dickey, Jan Genzer and co-workers was also covered by Chemistry World (Shrinky Dink origami powered by heat).
… And finally here’s the original research paper
