The art of projection is nothing new but it when done well it nonetheless is still pretty amazing. An example of this is the video by director Filip Sterckx for the Willow track Sweater. Created using just 3 projectors, a floor and two walls the result makes you want to star in your own fantastical adventure.
On another note, my friend Nic's band Cogel just released their new single and video incorporating the magic of projections too. It's rad. Check it out here.
