Today's short is the delightful Gulp from Sumo Science at Aardman (animators). It was filmed on location in South Wales on a Nokia N8 mobile. According to notes about its making, the largest scene in the film was more than 11,000 square feet long, which set a record for the "largest stop-motion animation set".
The sand artists are from Sand in Your Eye, in the United Kingdom.
(My thanks to my friend Judith HeartSong, who first posted the video on FaceBook.)
