Edit 3D mesh data in VR. You can edit mesh as if they were a real object in front of you. When you are finished you can export the data to any other 3D app. You can also use a node based system to apply functions to your mesh data.
I want to love it - but the UI... Icons, icons, icons as far as the eye can see but nary a tooltip to be found. :-)
Seriously - icons are great but only if they're meaning is obvious and there aren't too many of them. Otherwise they require laboriously memorizing their function.
