Make Your Own Diffraction Grating Kaleidoscope #ArtTuesday

Love a good kaleidoscope! From jbumstead on Instructables:

Kaleidoscopes create impressive visual displays by simply turning a knob. Here is a great design by randofo. Colorful displays can also be created with diffraction gratings. The visuals become even more stunning when you turn one diffraction grating in front of another: here is a video with lasers. This gave me the idea to create a diffraction grating kaleidoscope that makes it easy to turn the diffraction gratings for beautiful light patterns. One thing that makes the device different than usual kaleidoscopes is that it generates different patterns depending on the light source you are looking at.
