I've read a couple of stories about people from magical places being amazed by technology. The sort of technology they were amazed by was how we could cause light by just flicking a switch, and we could cause hot or cold water to flow into our sinks and baths by just turning knobs.

Just the other day I was watching a classic Doctor Who story (Battlefield) where the Doctor remarked that any sufficiently advanced magic was indistinguishable from technology. The writer commented that the costumes did adequately convey his intent, but that was his intent.
