I am more of an ideas and developer and not a designer (as you will soon see). So doing this for fun and to scratch an itch.
Started with my interests and looked for opportunties for badges. I focused on windsurfing achievements.
I then drew some stick figures sketches to represent achievements. "Up and running" and "beach start".
The focues on early ideas for achievements - I like crops...
Early days yet.
First attempt at a badge - for "Up and Running"
