Flow follows alot of your modern magic rules, but is still beautiful. Technically it's an old effect with a modern method, but aren't alot of these effects?
I would still say Flow relies too much on shock to be beautiful. The reactions are WTFZOMG!!!!!! reactions, not reactions of pure, true amazement. Watch this video, then rewatch the video of Flow. Flow fools me, the method is definitely well concealed and I have no idea how it's done, but next to that, there's no magic. And yet, the video I linked you to has no visuality at all, no sudden surprise that makes you wonder if you just saw it. It's just pure magic.
