Bridging the Gap

I need help...in locating irritating gaps. I started a project many moons ago and am revisiting it. It began by taking photographs of unconsidered spaces, you know when someone builds a shed next to a shed and leaves a gap that is not big enough to use?
Well if you have noticed any of these could you please let me know where they are or take a snap and post them on here. I am mainly looking for structural/architectural/man-made examples but if you come up with anything different then I would be keen to see.
