If you want to see E8 in virtual reality, check out the “Theory Of Everything” region at OSGrid.org
Of course, you will need an SL viewer and an avatar to get “in-world”.
Yes – that’s right, a possible Theory of Everything on a t-shirt
BTW – I left a copy of one of my E8 3D projection obects in Wizard Gynoid’s 7K E8 @ Butler CollegeIThttp://slurl.com/secondlife/Butler%20College%20IT/198/75/1001
It is the smaller white one next to the very nice larger (and better) green projection that Wizzy Gynoid, Desdemona Enfield, and Garrett Lisi created.
