Computer-generated special effects make us suspicious of anything we see on the screen.
So when we first saw this incredible Dr. Seuss-looking contraption in the middle of a forest play Bach's “Jesu, Joy of Man's Desiring” (in a commercial for a Japanese smartphone), we immediately had two thoughts:
“Is that real?”
And, “How did they do that?”
The answer to the first question is a resounding yes. I recently came across this two-minute video that gives a glimpse of how they did it.
Can you imagine how much time it took?
