Blender user Felix is a PhD student in physics at Hamburg University, Germany. Not only did Science accept his paper (and his team's, I presume), but they also picked their illustration to feature on the cover. I don't have to tell you which software he used to create the image, do I? ;-). Having your work featured in Science is no small feat, so congratulations everyone!
First, we submit a manuscript for publication, presenting our groundbreaking research. After a manuscript gets accepted (the hard part), they ask you for a picture that might go on the cover. Out of all submissions (~15 to 30, I guess), they pick their favourite. It's ours, hooray!
