tangent lines

You know that thing when you're driving through an area and your radio gets good and bad reception? Or when you are in a building and the only place your cell phone works is the northeast corner? I always wonder what fourth dimension traffic is really affecting those waves. 

hmmmm..... I wonder what would happen if I stitched a line at each seam of a composition. Would the composition show hot spots or areas of greater traffic? better reception?
