More illustration than logo for Nerd Merit Badges - a concept that will only makes sense if you're familar with scouting and in particular American scouting:

Whenever you'd fulfilled certain criteria, say learned to tie knots or sold enough cookies you'd get the cookie-selling badge to put on your sash. Replace "scout" with "nerd" and you get it - you'd probably need to replace the sash with a cubicle wall, but the cubicle wall is to the nerd what the sash is to a girl scout.

The broken and repaired glasses are the universal symbol of the nerd - don't tell us eighties movies haven't taught us anything useful, so these became the Nerd Merit Badges logo in a heartbeat.

Keep checking their Nerd Merit Badges website, new ones are constantly being made.
