I LOVE CLUTTER, AND I JUST WANT MORE. However, I like the rotating idea. it gives you an excuse to pick them up, and play with them. I find, I get things, and put them on display, and don't play with them much, but when I dust (like once a year. :lol) I pick each thing up, and have a blast fidgeting with it.
Plus, the less you have out at once, the more it showcases those pieces.
That said, if you do decide to store them my Girl friend works for MTM plastics, who make a number of gome padded gun cases of all different sizes and shapes. She gets me free ones if I need them. (You know the rejects, the ones that them might not make anymore, or are the wrong color, or whatever, but still look great, and work fine.
) I'm a very lucky man, she's a total sci-fi nerd, and she gets me cases for my props.
