At What Makes Me, you can create a “cube” using photos, video, and audio (you can easily grab them off the web our upload your own). Your creation is supposed to be a representation of “you.”

It’s from the Australia Council For The Arts and, theoretically, it’s supposed to just be for Australians, I guess. But they invite people to make as many cubes as they want, so my sense is that they probably have a lot of space on their servers and won’t be too concerned if non-Aussies contribute. No registration is required, other than your email to save your cube.
