Very few lol, I haven't even tried it myself to be honest but I couldn't quite think of a better way to express what I meant. It's more that if you've ever looked into the kinds of tricks that are necessary to do it, and compare that to how trivial it is to splash a simple texture onto a wall, that's a good demonstration of why they're so much more magical.
Completely off-topic, but how many people would you realistically expect to answer “yes” to that question?
