Press the green flag, and this project will randomly select a QR code to display. For extra surprise, the QR codes have the Mii names edited out. Then, you can scan the QR code with your 3DS or Wii U GamePad to see which Mii it is. So far, there are thirteen Mii characters. More QR codes will be added soon.
I saved the QR codes of Miis on my 3DS on my 3DS. I then sent it over to my phone and uploaded the images to Google Drive. Then I downloaded them on my Chromebook and I put the codes in here!
