Lights! Camera! Action! I have analyzed your mental poop (pp. 2 - 4) and came to the following conclusions. These conclusions are not a complete analysis and are not meant to be taken seriously, because you are second-rate screenwriters and nobody takes you seriously. If they are at all accurate, it is because you keep sending me your unsolicited scripts.
light_chaser sees flames. The lines are vicissitudinous, wavy, and flicker back and forth, just like light_chaser's movie Light Chaser, a coming-of-age story about a young light chaser played by light_chaser who chases light from a fire.
Salvidian sees the tail of a merman. The lines are a wavy form, but that of flexibility like a fish tail, but on a colorless, headless, fingerless human person thing, the main character of Sleepy Shallow. the script Salvidian tries to peddle. The story is best described as Sleepy Hollow meets Jaws but without any of the good parts, because there is nothing scary about colorless, headless, fingerless merpeople.
Darkfire45 sees bacon. The lines are yet another wavy form, but that of the ripples of bacon. Darkfire45's love of bacon is apparent in his screenplay The Baconator about a pig running from the eponymous Baconator sent from the future to kill him, starring Kevin Bacon.
Reton8 sees stink lines. The lines are wavy, not from a fire, but from being stink lines. It should be no surprise that Reton8 wrote a screenplay entitled Everybody Poops: The Animated Movie and is waiting for improved smellovision technology. For now, stink lines will have to do.
Strop sees rippling back muscles. The lines form the strong contours of muscular back muscles of one of the protagonists of Strop's sci-fi martial arts erotica film Fists of Passion. It is as B as movies get. The plot is thin, but that's not why people would want to watch it.
gaboloth sees a seas snake with a large dorsal fin. The lines are a wavy with life. After the commercial failure of documentary thriller Snakes on the Seregeti, gaboloth shifted gears to write the scientifically inaccurate adventure horror Primordial, featuring deep sea adventure and monster sea snakes! Did I mention it was an automatic transmission?
kegaumongo sees the lines of a senyera. The lines are wavy because they are waving in the wind. The flag features prominently in kegaumongo's Catalan historical drama, Sorres de Barcelona, set in the 19th century of the coastal city of Barcelona, featuring soccer, love, and beaches.
soccerdude2 sees the trunk of a tree. The lines are natural lines of a tree. It should follow that soccerdude2 wrote some sort of nature documentary about trees, but no! Falling Trees is a documentary on thought experiments, philosophy, and Zen Buddhism.
Hectichermit sees a nose. The lines are wavy due to crookedness, possibly from destitution. Perhaps the most confusing movie on this list, Portrait of a Sad Man is a(n arthouse?) movie about an artist painting faces for some reason. There is no dialogue, only grunts, mumbling, and shouts of frustration... for 120 solid minutes.
Bronze sees a wobbly sword. The lines are wobbly, because not everything has to be serious. It should then be no surprise that Bronze wrote the screenplay for Equilibrium: The Legend of Wobblesword, a comedy adventure about a wobbly knight and his wobbly sword.
goumas13 sees the trunk of an elephant, and a window! The lines are wavy with life and perhaps, curiosity. Inspired by John's elephant games, goumas13 wrote (an outline for) Irrelephant, a documentary on John.
And that's they way your movies came out.
Onto your next movie. Can you show me what this is?
