I did one art and science innovation.that is Artificial Rainbow Designing images.other name is DLD images (Desperation of light Designing images).the main objective of this innovation we can create Image whatever we required by using Artificial Rainbow.An owl silhouette projected with rainbow spectrum light. The feather curves show smooth diffracted colour transitions.i strongly believe this kind of innovation use for showcase in our homé at the same time it use also as a mini projector to teach lessons in Poor countries because it is very low cost.
