How far from the window can a plant sit? Slide it and see

A plant on a sunny sill and the same plant three steps back live in two different climates. Light drops quickly away from the glass, and which way the window faces decides what kind of light you get in the first place.

Slide a plant around a top-down room plan, switch the window between south, east, west and north, change the month, and watch the bright, medium and low bands move. Then measure your own room and match each plant to its spot.
