Hey, for any curious for the format, there's a really cool program in beta right now that helps you to easily build a virtual reality art gallery.
Check it out. Sign up for the beta, make a gallery, and help them add any features you think they're lacking. Right now this is not an eCommerce site, but it is something they are thinking of adding in the future. I just downloaded it earlier today, it's UI was very intuitive for using one of the pre-made gallery options at least. I haven't experimented with building my own gallery design yet. Just imported my photos and used one of their floor plans.
