Great idea.
Never occurred to me.
Made me think of those accordian/catapillar style containers that collapse.
And Bring Your Own shopping bags: the "S" stores seem to be totally unprepared for self-packing (except Superstore). They should have a dedicated line for that.
The leaving the lights on issue is more personal to me. While I don't have a "diagnosed" seasonal affective disorder, I can feel grey during the winter. I live in a small apartment, really only 2 private rooms (bedroom & bathroom) and an open living/kitchen space. It's lighted with halogen lights, better than incandescent, not as efficient as flourescent, but with a broader spectrum. I believe I notice a difference in my mood from the bright colour of their light. Sometimes when I come home from work I turn everything on just to make me feel more energerized on a dark afternoon. Sometimes I like to sit in the dark and watch the colours fade outside.
