The Lightcoder by artist Geraldine Juarez is an analog urban communication device in the form of a bag made from reflective mylar that uses a light source to encode messages into morse code. The bag itself comes with the Morse code alphabet guide, a map of Manhattan, a broken digital compass, lantern, aspirin, rad-block, dust mask, utility knife, hand made shape-lock cups, and fire starters. The result, says the artist, is a symbolic object that explores the possibility of survival in urban environments by bringing out the vulnerability of modern digital technologies and communications devices.
