I keep all the photos that i take that have this sort of effect where the sunlight/sunset light beams out of one window and hits the camera lense, and the idea that you can get really bright colours, each time depending where abouts you are. For instance i was on a coach on the way home from a trip to london and  i remember it being really cold but really sunnny, and i thought it was a nice sight looking at the sun shining inside.
