Alex Griendling, who works at Google during the day and his own projects at night, created a Calender last year that depicts time traveling geekyness throughout the year. This year he is back with another Time Travel Calender, with improvements plus cute icons for famous nerdy shows, comics, and video games. It is a crowd-funding effort using Kickstar, and apparently extremely popular because the project is already funded. Which means, for $25 you can get your very own Time Travel Calender. Or, you know, the holidays are right around the corner, so this would also make an excellent present for the office going drone nerd you know and love. And yes, there will be references to Doctor Who.
