In my [1]#TimeTravel experiments, I started (finally) installing
  an Eclipse (and Netbeans - can't decide), along with all the
  prerequisites - all because I was curious about a particular 3D
  library which does everything but feed me supper. Then I was
  like, "Ok.* What's all this crap I'm downloading?* Oh yeah.*
  More than I'll use". So, I went back in time.* I thought: "Ok.*
  Java's a virtual machine.* There's lots of virtual machines.*
  What else is out there?* Where did JAVA steal their ideas from?"
  Of course there's whole machine emulators like VMware (I like
  VMware) and VirtualBox (which I have but haven't needed to use
  yet) - but I was looking for JAVA's daddy. So: Here is JAVA's
  daddy:* The USCD P-System. And here's how to get it to work on
  your futuristic computerification device.* I fumbled my way
  around and created a virtual volume with a few blocks, then got
  bored and wanted to share* and so I made this post.
