RIPPLES -recreating the effect through light & shadow by Samir Saurabh from india
designer's own words:
This Project is basically creating interactive space where person can enjoy the continues change in the abidance which gives him partially controlled movement i.e. when person come close to any of the unit it start closing down and give gives him space and eventually ripples started forming, each unit interact with each other so change in one unit effect the movement of other. here we have created small scale prototype. material used for prototype is 4mm medium density fiber board.
