Excellent art lesson, Sir Javier. You explained things very nicely and elaborately. I will try to use the information that you're writing here :).
Great VR art as well, I didn't know that it's possible for a 2D art to envelope the viewer like that O_O, pretty nice.
You're welcome señorita ! Feel free to ask me as many questions as you need and join the SpheriKus Commando!!
