One time, I noticed that the blind in one of the windows in the house produces the pattern shown in the picture during mornings. I couldn't let the moment pass (though the pattern is always there during sunny days). Light is very important to photography because it gives subjects shape and dimension. But sometimes, light itself can be the subject. I set out to prove it here.

(Disclaimer: I don't think that there is an element with such an absorption spectrum. I just noticed that this pattern "can" be similar to one.)
