Ga-nime (画ニメ, Ga-nime), a portmanteau of “illustration” (画, ga) and “anime”, is a relatively recent trend in Japanese animation to create highly aesthetic short anime films using non-traditional animation techniques, often directed by artists who have limited involvement with the anime industry.
Typically, these films will utilize a series of illustrations accompanied by voice acting and music, with the only motion provided by extremely simplified limited animation, computer animation, camera movements such as panning and zooming, or stop-motion animation. They are generally produced by only a handful of staff members, with the director often writing, illustrating, or even scoring the piece themselves.
Since 2006, Toei Animation has produced several ga-nime, directed by various notable artists, including Yoshitaka Amano and Keita Amemiya, on a variety of subjects ranging from original stories to adaptations of the works of Osamu Dazai, Sakutarō Hagiwara, and H. P. Lovecraft. (Wiki)

This reminded me of the animation segment from Robot Carnival called Cloud directed by Mao Lamdo with music by Isaku Fujita.
