My get pushed partner @livvy challenged me to make an abstract collage. Here is a collage made from just one shot of a bit of my pantry door (with textured glass), reflection of that texture in the dark (it was dark outside) side window of the door to the back porch, trim around the door, and a bit of the door itself. The larger center piece is the way I took the shot with the camera tilted to get diagonal lines. The small colorized version in the center is the same but rotated to straighten it out, with the doors in their natural vertical instead of diagonal.
