Sending Dots from Abroad

Simon Mortimer, in his final year at Lincoln School of Art and Design, designed this piece titled "Dot 2 Dot." It's a typographic experiment using connect the dots to spell out well-known worldly greetings on postcards. The words include ola, aloha, hello, bonjour, guten tag, and ciao. While the idea is original and I like the interactive aspect of the postcard, the color palette seems a bit dated to me... yet so are postcards, no?
