The 2012 Time Travel Calendar, funded via Kickstarter, places time travel events from TV, Film, Video games and Comics on a single timeline.

A select number of people also received a button pack from the future (3rd image). Everyone who helped fund the project received a postcard (4rd image) from the future featuring a moon base with the Earth in the background. 10 people chose their favorite icon from the calendar to be put on custom buttons made just for them.
