In this video by Minnesota artist and animator Caleb Wood, you'll find a clever twist on a traditional animation technique. Wood used a blank wall at the Prøve Gallery in Duluth, Minnesota to draw a series of freeform icons in semi-straight columns — or as Wood calls it, "a continuous vertical freehand digression" — that look, from a distance, almost like Egyptian hieroglyphics. Scan them from top to bottom, though, and they start to come to life, doodles morphing into other doodles in a weirdly mesmerizing way. It's like one of those flipbook animations you made in grade school, only on a much larger scale (and on a completely flat, un-flippable surface). The piece is called Plumb, and is part of an exhibition that's opening this weekend, if you happen to find yourself in Duluth. If not, check out the video above.
