I love the Olympic posters! I think a great project would be for students to make their own Olympic poster artwork based on a famous artist in history. It was have to reflective of that artist's medium and style. They would also have to pick a sport that helped communicate both the artists style, but also the sport itself or stay within the Olympic theme and conveying an idea about the Olympics.
"The posters were unveiled at Tate Britain in London along with the programme for the London 2012 Festival. The full list of contributing artists are Fiona Banner, Michael Craig-Martin, Martin Creed, Tracey Emin, Anthea Hamilton, Howard Hodgkin, Gary Hume, Sarah Morris, Chris Ofili, Bridget Riley, Bob and Roberta Smith, and Rachel Whiteread."
