Artist Nacho Guzman (cool first name, BTW) has created a video that shows how lighting can really affect a mood and situation. Partly an homage to Heni-Georges Clouzot's effect used in his 1964 film, "L'enfer," this video is amazingly psychedelic and beautifully disorienting.
Please take a minute and fifty one seconds to sit back and enjoy this preview clip.
And some GIFs to watch until your eyes bleed.
