I have actually quite the opposite point of view. I actually aim for the things I build to feel/be magical. Yes everything is still explainable but usually the system is sufficiently complex that even as the creator you can feel overwhelmed. Recently I've built a small project (I've made a show HN yesterday which btw didn't get any attention) which felt quite magical and futuristic : A remotely controlled robot which displays some deep art. When novice people interacted with it, they felt a bit of the magic of technology, just like wielding a wand, it responded instantly to their will. I enjoy creating things which may have unanticipated effects. Recently, I have been interested by the theory of complex systems and in the way it is similar to real magic, as opposed to the magic you describe as an illusion.
