This year I felt a bit nostalgic and created a Geek Christmas Card inspired in the old franchise vide games Where in the World Is Carmen Sandiego?" and its show.
I was surprised when back in spring I found the Google Eart version of it "Where on Google Earth is Carmen Sandiego?".
The game was designed to be played in PC and not in mobile platforms.
