Interact, explore, and share art in the outdoor environment. We have placed transmedia artwork in urban settings in Davis, Ca. Silent images, paintings, and sculptures invoke memories from the past. Extreme Signpost has fitted pieces with RFID tags embedded in concrete. They are highly resistant to rain, snow, and tropical sunlight. Each tag can be updated on the fly using RFID enabled cell phones. On the sculptures, we have written links to poetry, music, and video files. The artwork contain an interactive surface that serves as a blank canvas where artists, participants, and visitors can leave messages and stories.
