Last year, Telstra worked with OLPC to develop a media campaign promoting OLPC in Australia, and raising money for 500 XOs to be sent to aboriginal communities. This month they took home an award from the Cannes Lions festival for media, in recognition of the excellence of that campaign. See the Cannes entry for images and screenshots of their designs.
Rumour has it that the followup this year will be astonishing — I can’t wait to see it.
