Redesign an existing poster 50 times. Present it in a form that relates to its content.
My starting point was a 1951 concert poster by Josef Müller-Brockman. See a selection of my iterations below. ↓
The presentation used a recording of a piece advertised in the original poster (Chopin's Piano Concerto 1) performed by Alexander Brailowsky, the soloist from the poster. I animated all 50 designs to dance along. ↑
Fun fact: The animation was painstakingly (but lovingly) assembled by saving many hundreds of Illustrator artboards and compiling them in iMovie. (I hadn't discovered After Effects yet.) Animated mockup is, of course, more recent.
