Starry Night
From Tardis Wiki, the free Doctor Who reference

Behind the scenes
Vincent and the Doctor features a scene in which the Eleventh Doctor, Amy Pond and Vincent together imagine the night sky as Vincent sees it, ie. as depicted in Starry Night.
Later, The Pandorica Opens introduces another van Gogh painting, The Pandorica Opens, very much in the style of Starry Night, but with an exploding TARDIS.
