thinhnghiem Posted September 4, 2013 Report Posted September 4, 2013 Dear all, We can create very beautiful scenes by a simple experiment that we can do at home Using a kaleidoscope. Put a LED source behind it to emit red color light to its back The red light will be scattered by the kaleidoscope to make marvellous images I attached here an example. As you see, the scene turns red, and it become blinking We can improve this by using LED with green color, or combine red and green ones Quote
