Total Internal Reflection

Total internal reflection is the principle of the viewfinder in a SLR. Basically if the angle of light hits a glass surface at a certain angle, instead of actually passing through that glass surface it is reflected as if the surface was a mirror. I'm not quite sure what was happening at the corner of this shop window. There appears to be reflections everywhere. Stiill I must say, I do like the chaos it throws up. Last shot of the day-what a doozy!
