Rather than clutter the sidebar of the Snippets Playground too much, here are the Snippets Playground badges all in one place for you to copy and paste to your own blog accordingly.

The others are:

When you're a top pick 'Gold Star' challenge entry

When you're one of the fortnightly 'top picks'

When you're on the 'team of designers' for each challenge

When you're a 'Guest Designer' by invitation
