kijete is an app for Pebble that allows you to display Code 128, Aztec, Data Matrix, PDF417, and QR codes on your wrist.
It is a fork of Skunk by Harley Watson, and is so named because in toki pona, a skunk would be described by the word kijetesantakalu, or for short, kijete or kije.
It swaps out a ruby web app for config and barcode generation for a fully client-side JS application.
Its Aztec code support actually works, and it generates codes that are identical to those in my Google Wallet, which is generally a desirable trait. It is using the 2D-Barcode library.
