This sort of chameleon-like, shade-shifting elements could be on the horizon, thanks to a photographic procedure which is been resurrected and repurposed by MIT engineers. By making use of a 19th-century color photography technique to modern day holographic elements, an MIT staff has printed large-scale illustrations or photos on to elastic components that when stretched can rework their colour, reflecting distinct wavelengths as the substance is strained. The researchers created stretchy movies printed with detailed flower bouquets…
