I thought this packaging was so amazing! " Apart from the utter tactility of the package, Motion Blur includes transparent typographic windows produced by laser cutting the title into the sponge. When the book and dvd are pulled from the sponge slipcase, they flash through the lettering, creating a kind of blur. The futurist painters, concerned with simulating Machine Age dynamism, also used the blur as a symbol of progress. For most of the twentieth century, typographers and photographers created static blurs as indictors of forward movement and thinking."
