In FractalMUD we see a 2-D cross section of the 3-D pixel volume at a time.
This is a true fractal, therefore, we can zoom infinitely into it. We can also roam in the X-Y, Y-Z, and X-Z planes. Each time you zoom in, you triple the number of steps you can take in any direction.
If you venture where no one has gone before, you will be creating a new "chamber" in the MUD and you will have to wait a minute or two for the image to be computed.
Warning: the Oracle is uncensored.
