Finished carving 3 Dr. Mario virus stamps and listed in the Sunshine Cupcake! Etsy store. Red, Blue, Yellow or a set of all three.
As a side note, you can subscribe to our Sunshine Cupcake! Flickr set.
I even went so far as to (attempt to) record a video tutorial on carving 8-bit rubber stamps. Here's a little taste of the awesome that goes on over here in Cupcakeland.
