Well... it's better than those who are not thinking, I guess. I'd be really concerned about the paper/curtain weight, especially in a house with small children or pets - that one is potentially lethal in several different ways. The drinking cap is, I think, a response to the beer caps that look similar - not something any of the middle school students I teach would be caught dead with, I strongly suspect (and any that would, would get the crap beat out of them). The soda pop people are, I think, the most creative - I have friends who might decorate their fence with items like that - but again, I'd be worried about children and small pets.
And for all of these items, most people I know would have to go out and buy at least some of the materials - the bags they have wouldn't be the right color (the plastic bags around here are mostly white or brown), the kid wouldn't have a hat s/he was willing to part with, the soda cans might be available, but not the fabric and/or paint to decorate them with.... I understand and appreciate the recycling concept, I just don't think items like this are realistic.
