Wiki updates:

• The 'Fun & Games' section was expanded. Before it only contained the two puzzle sequences created by cyberspace users. Now, it has a bunch of other stuff on and about cyberspace, a mix of user- and khan- created content.

• I added a full description for @digitalgrease 's cyberspace client.

• Not really a discrete update, but over time a few more people have been added to the directory of user pages.
