I need to put out a #teachtheweb all-call to MozTeach to help me get these things into the Open Badges Initiative; nevertheless, here are some handcrafted #nerdcamp badges for the participants at our inaugural session.
Feel free to edit, remix, and use them elsewhere under the Classroots.org CC-By license!
[Workflow addendum (added on 4/5/13): I grabbed a badge template from Pomax's github repository and then drew and colored my own badge layers over it using a Bamboo Create pad and SketchBookPro. I used a Scratch Cat image from ilearn.cc, but would like to redraw the cat myself soon. I used Acorn to make the badge backgrounds transparent and to crop the images.]
