>>4334329it is the self interference of light waves within a lens which creates this pattern
>>4334324when I was younger, I created a homemade laser interferometer and used a camera lens to format the final output of the device. I was able to see (and morph/interact with) this exact pattern as it was projected onto my wall. with miniscule adjustments to the air between my mirrors, I was able to create immeasurably small disturbances in the fluid and witnessed an evolution of the interference pattern which I only wish I could describe. truly a beautiful and complex sight which I will never forget. light itself is an amazing entity and we are lucky to have engineers who have come before us and built these cameras to capture it, even for a moment. the interplay of light is one of the greatest mysteries of the cosmos, and one we still work on understanding today
