When I was a kid I had a recurring dream that I had a special machine. I loaded plastic pellets into the machine, then if I designed something on paper & fed it into the machine, it would create what I had imagined.
Now I find out that such a machine exists. See the following link. (Thanks Ilya Vedrashko for pointing it out.)
