UN Habitat just asked us to write a summary about how well the Cape Town WaterCube went last month, so I created this thumbnail collage to feature images of everyone who came in and talked to us. We got more than 70 short video interviews online from the UN’s World Water Day event in just three days using a good internet connection, three MacBooks, a few Flip cameras and a small team who don’t normally do video.

I laid this out in Adobe Fireworks, which is a handy app I’m now using for this kind of thing. When I get a chance I’ll pull out the Blip.tv thumbnails from the two previous Stockholm WaterCubes, too. Then we’ll have a collage of more than 300 people, all talking about their work to tackle the world’s problems related to water and sanitation. It looks like we’re going to run another WaterCube at this August’s World Water Week in Stockholm. Keeping it simple has made this much easier to scale. So here’s to the next hundred, I say…

(And maybe in September we’ll be able to render something that looks a bit like this).

Watch all our interviews online at http://www.watercube.tv or have a look at our Highlights of Cape Town WaterCube.
