Signature piece is about the recording and reproducing of sensitive motion through the transformation of energy into movement. As a series of urban mechanical sculptures the "pieces" would emerge from the "cloud" and invade man made modem environments. For the purpose of this project we decide to focus solely on one sculpture we named "Signature Piece." A significantly simple devise that can reproduce any one persons scripted signature on site. Utilizing the ICloud signature piece is able to send its DNA anywhere it so chooses, encoding individual signatures into its design as it is produced. Using the DNA given exhibitors can produce the machine on site via any rapid prototyping method. Making the availability of this machine limitless and exponential.
