New England Aquarium Invites You to See Turtles ... EVERYWHERE.
The New England Aquarium's "See Turtles" campaign is an appealing exception to the no-pun rule. (Also, we like an effort that doubles as justification to take hallucinogens.)
Online banner ads -- which are also cute, if a little Clip-Arty -- include Snowman, Cocoa and Car. (Forgive us if these links break; they're hosted by Mullen.) These are slightly different from their print counterparts: in them, ordinary things take the shape of turtles over time, taking advantage of the 'net's ability to seize roving eyes. Frankly, the print stuff is better.
Work by Mullen/Wenham, MA. There's also radio material, which we didn't get to hear.
