German artist and animator Henning M. Lederer just released another collection of 36 animated vintage book covers that are trippy as hell. The collection of books he animated runs the gamut in terms of discipline, but most of them focus on educational texts. Chemical Calculations. The New Technology and Human Values. Parapsychology. The Psychology of Imagination. Non-Freudian Personality Theories. Lederer’s animations, particularly when their paired with music by Jörg Stierle, are all a bit of a mindfuck if we’re being completely honest. With that said, that hasn’t stopped us from watching the shifting lines, rotating squares and pulsing circles in the images and video multiple times in a row and pondering how they would have affected our high school grades if they were physical products. Check out the rest of Lederer’s work on his site led-r-r.net and the source material on the Julian Montague Project just so you can see how much work went into creating each animated cover.
