Welcome to the first Doctor Who's Day roundup of a new year, and with change in the air we've been trawling the internet for fan creativity and official Whovian news and events to gather together into a big pile of intergalactic astonishment and Gallifreyan glory.

And we begin this week with the various fan responses to "Twice Upon a Time" that have been rippling across cyberspace since Christmas Day. Now that the era of the Twelfth Doctor is officially over, YouTube has seen a fresh influx of clips compiling his best moments, each taking a slightly different emotional trip through his time in the TARDIS.

There's this emotional roundup from TheGaroStudios:
