Big money should no longer be an obstacle when creating music videos. This really fun one from director Dennis Liu of Radical Media for indie artist Sia was done for "a few thousand dollars". "We somehow thought doing a live action video game in camera was going to be easy but actually its really freaking hard, says Liu. We had to push through 40 yards of foam core through a tiny track to get the words moving. But the strange thing is, it's always fun when it's over."
