Thread: "Your expertise"

Hello!
I'm new to the group and sorry to be late to what looks like a cool party.
Like some of you, I've made my way here because of my general interest in
the fourth dimension, not only as an object of understanding, but also as a
sort of frontier to conquer. To solve the 4D puzzle is to win.

By day I work as a simulation technology specialist at the University of
Virginia. On my own time, however, I'm part of an open source collaboration
called Hyperland that is building a simulation of four-dimensional space
and a user interface so that users can interact with 4D objects and other
users moving in 4D. The project's web content is hosted and maintained on a
platform known as the Open Science Framework, which is supported by the
Center for Open Science, for which I have done some volunteer work. You can
learn more about all of the above (including me) via the link below:

Best,
Ben

Welcome, Ben!

I didn't realize that you are building a *shared* virtual 4D world.
That's very audacious! Be sure to place a 4D Rubik's cube on your coffee
table so users can help each other to learn to solve it! It can get
lonely doing it the normal way. :-D
