This ad from Publicis & Hal Riney for U.S. Cellular is, without a doubt, the greatest reverse-melting crayon ad ever made. It's hypnotic, creepy, trippy and ever so vaguely sexual, with perfect portions of each quality skillfully mixed to keep the brand message from being overwhelmed. The clip provides a memorable visual metaphor to illustrate the point that with U.S. Cellular, users' data is never lost for good. To see the same basic idea handled much differently, watch this ham-fisted (actually, cow-fisted!) Draftfcb commercial for Qwest. Psychedelic crayons vs. hands-in-a-heifer! When it comes to data protection, I think the choice is clear.
