So, if you don’t know what goggles are, I suggest you go to their website: http://goggles.sneakygcr.net/  

Follow the instructions, go to the doctor who tag, the doctor who official tumblr, and your own dashboard, and turn on the goggles thing.

It allows you to leave and write secret messages on part of a web page. The Doctor Who Official blog has so much secret messages drawn all over it, and scrolling through all of it was really entertaining…
