Stained Glass Window Coded in P5

I made a series of graphics with code on the theme of creating graphic representations of things around me that I find interesting to look at. I used P5 to create graphics and posted the series on Glitch. At first I thought this would be a pretty simple thing to code, that was until I decided to represent the blurred shapes showing through the window. One thing I learned was that the filter(BLUR) function can be placed such that it only affects certain objects in a sequence of code.
