But ... umm ... What kind of technology did you use to create this file you uploaded? It works as a thumbnail, no doubt about that. But the full sized image is garbled with compression artefacts. Hey, the iSight camera on your MacBook can do far better than that! :)
Yes that one's not from my iSight, hehe, it's a still image scooped out of a Quicktime video file. The image works well at its original size and smaller but DailyBooth has it at 200% here ;)
