Avant-Garde cinema in My Own Private Idaho's

The scene I think that is Avant-Garde type of cinema in My Own Private Idaho is the where a stranger walks into a shop and some of the characters are on the front cover and begin to talk to each other. I mean something like this was on the Brady Bunch but to have the text of the magazines stay in place and as they move. It seems like some animation and certain cutting of film took place to make this scene possible. The scene begins at 17:34 where you see the camera starts at mid level building wise showing the name a shop. Given by the ad underneath the sign it seems to be an ad XXX shop. 17:35 the camera starts to tilt down giving a view of front of the shop and three people in front. Shows rough neighbor hood, kind of dark and dingy. Then at 17:40 the camera tracks to the right and down of the shop with the three people in view. The music is what I would call Indian music. As the shot lowers you see that the three people are in fact men and gives the impression it is a gay XXX shop. At 17:45 the sound of boots come in and is getting closer. At 17:50 a cowboy comes into full view and enters the shop. The camera flashes inside at 17:57 and a mid shot of the cowboy at his waste as he passes through to the back as the camera tracks him but slowly so that at the end he is in full view while flashing some magazines which could be important. At 18:11 we see Schott on one of the magazines and begins to talk about his experience as a model. This is also where we finally learn about Schott. At 18:49 Schott interacts with Mike on another magazine cover. The covers have at least mid shots. At 19:04 the effect comes into view, the actors on other magazines begin to interact teasing Schott about being able to come into money while all of the actors being in what looks like total different spots/magazines. The purpose of this scene seems to be to get the understanding that Schott has money and show more of the Gay culture.
