Hmm.....wonder if there is any relation between the two series. Looking at the artwork, I would guess no.

Funny, isn't it? The things we treasure are generally physical. Perhaps it is because there is a greater sense of loss when they are destroyed.

Maybe, but I think that something physical also appeals to more of your senses. The smell of the paint or the scented stickers. The ability to feel the texture and the subtle "defect" that makes it unique. It's a total package...
