It is a waste, on the other hand, you don't end up having a shelf-load of dusty plastic things slowly getting bits knocked off them. When I was making models first time round, the shelves of models were a constant reminder that I should have been using my time to do more interesting things, so I kind of resented them.
This time round, I've got plenty of other interesting things to be doing, so I don't feel resentful.
Maybe there's some sort of compromise to be had where the shelf is actually a very slow-moving conveyor belt which takes a year to roll something from one end to the other, and there's a bin at the end of it.
are you KIDDING ME? That's the best web cartoon ever right there! "Then I will glue on another box" it's like some kind of Eastern Europe film with all pathos and whatnot.
I've always seen the red things in that icon as levers, one for the box, one for the glue. I've wondered what they'd do if pulled? Perhaps it's PB's reset switch, or turns the lights out in Preston. But, today I've looked a little closer than I ever have before, and they could just be stirring sticks. I can completely understand why you'd need one for the glue but why stir nails/jigsaw pieces?
