These are my links for March 11th:

• Greeble Earth – reminds me of my Terra Fermi map with 3D buildings added.
• The Balloon Project: Amsterdam and Berlin Aerial Imagery – The Balloon Project is charming in its simplicity – Luca and Ira send a video camera up into the sky hanging from helium balloons chasing it from below on bikes – and the results are fantastic.
• The Guardian Open Platform – The Guardian announced the launch of The Guardian Open Platform, a suite of services designed to give access for developers to Guardian content. Of course, this follows hot on the heels of The New York Times’ API releases, but where is the Washington Post?
