Fun optics-related photos.

Hold up a labeless CD to the room lights to see a ring of rainbow colors.

Coat a piece of glass in Rain-X and spray water on top to create a water lenslet array.

Looking at a flashlight through a 2D diffraction grating.

Looking at a toy through the bottom of a glass. Each blob shows a perspective view.

This is the beautiful pattern  of light created by a glass of water in front of a projector beam.

Notice the rainbows!

Those aren’t my house keys!! They’re holograms (made by J. Lee).

Diffraction of light is a lot like the wake of water behind a moving boat.
