I'm Platonist. I was the CWU Mathematics Club Webmaster, and I tutored mathematics for many years and still occasionally help people in maths & other chat rooms, besides asking questions myself.
    The following are my ideas of polychora (four-dimensonal shapes) sections unfolded, with perspective (and 120-cell also without it), into R² (two-dimensional space). Originally, I thought these were regular polychora, but actually these are sections or other shapes.

    My CWU software engineering course senior project was working on the Wind Farm learning Resource (exhibited at Wild Horse Wind Farm) for Puget Sound Energy. I work on SlackBuilds, told the z88dk project the code fix that ported z88dk to NetBSD Unix.
    I did a small graphics demo (intro), which is on my demos page.
    I have written several computer science papers I may put here later.
    There is no system but GNU, and Linux is one of its kernels. GNU is the greatest, most glorious. Well, so are BSDs and other Free/Libre POSIX-based systems.
