Hello Edward,

Welcome to the group! It’s great to see your interesting and
enthusiastic messages. I encourage you to introduce yourself and tell us
about your life, work, hobbies and your experience of solving the 4D cube.

About GreatStella, yes I’ve been well aware of it starting in 1999 but I
doubt that many others on the list know about it. That was when Robert
Webb and I were both on a polyhedral mailing list hosted by Magnus
Wenninger. It was that list that helped him to define the feature set
and I particularly liked his stereo modes. That list was understandably
more interested stellations than I was though I see from the description
of the current version that he now has a 4D version which could make it
a very good tool for 4D puzzle makers. He also supports an "augment"
feature in his 3D version that could be very helpful as well.

I’m a huge fan of cross-eyed stereo and have lots of stereo photographs
<http://www.superliminal.com/stereo/> on my site. For that I use an
applet that lets the user select from a long list of possible viewing
modes. I always prefer cross-eyed viewing myself, and during my last
programming work on MC4D I did implement a cross-eyed stereo feature
because I believe that it is very valuable for 3D work like this, but I
backed it out in the end because I wasn’t able to get it perfect in the
time that I was willing to spend on it then. You are right that the
animations give a strong sense of 3D. The real value of a stereo mode
will be it’s ability to let the user keep the full sense of the 3D
projection when it is not in motion which is most of the time. We still
have the change set to work from whenever I or someone else next get the
urge to work on it. This is listed as issue #35
<http://code.google.com/p/magiccube4d/issues/detail?id=35> in our Google
Code issues list <http://code.google.com/p/magiccube4d/issues/list> and
it is my highest priority item. I encourage you to see what else is on
our list and to comment on them, star your favorite items, and add new
bug and feature requests.

Again, welcome to the list, Edward,
-Melinda
