for Anything [EPUB ebook] 

We call it a gismo.That’s right, a gismo.A bit difficult to describe. Like a cross, I suppose, without the top part. Sort of two arms on a stand.What happens is this. You hang something on one arm. Anything at all. A watch, a bracelet, money, anything. I supposed you could hang a locomotive on, only it’s a bit heavy.But anyway you hang something on and there on the opposite arm appears an exact replica. And I mean exact.You can’t tell the difference.So nobody need make anything any more. What you need you hang on the gismo. No work. No want. No starvation. No nothing.When you’ve got a gismo, you’ve got everything.
