And with Inception still going strong at the box office, plenty of people might still be trying to figure out its labyrinthine structure. Cinema Blend has put together a great illustrated guide to the five levels of Inception's plot. And an artist calling himself "dehas" has come through with an Escher-esque "Inception Infographic" that has already become widely popular as a reference guide to the movie. Check 'em out... but do beware of spoilers if you ain't seen the movie yet.
(Same goes for that Back to the Future chart... but if you haven't seen those movies yet, what the heck is wrong with you?!?)
