1. Elusive, theoretical construct of a forming mind.
   
   
2. The Phycon: a notable instance, created as a playground for a dangerous mind.
   • Structure:
     A loosely cobbled together environment sporting pantheons, aircraft hangars, stone circles, orbital stations, green hills, mountain streams, deep woodlands &c.
   • Purpose:
     The Phycon was created as the playground for a potentially catastrophic mind. The many environs comprised in its construction provide suitable housing for that mind's errant thought-forms.
   • Manifestation:
     The Phycon is most often manifest at times of deep thought, while the mind is combing the internet or entrenched in a book.

Note scrawled hurriedly in the margin:

It is with resignation that I have had to revise this definition with a heavy backspace key, as the old: "particular instance created as the alternate persona of a UCT Student" observed "spending much time ferreting around for information; esp. on sciences ancient and modern ... in the Labs (Comp Sci or Elec Eng),haunting bookstore coffee shops, Bouncing around club unity (11pm Sat-8am Sun)" was quite out-of-date.

In a melancholy moment the memory of the Phycon-that-was clatters hollowly in the vast expanse of the new; so small in comparison with the mindscape we observe today -- so small, so limited and so safe.
And now we merrily soldier on. Broader horisons, innocence lost.
