This is kind of funny. And it is a "self portrait", too! (Well, in a way...)
Only is the reflection as such not that very, very interesting. But the distortion given by the "stressed glass" (why do you call it that?) adds a fun element to the photo.
I called it that because the settling of the building stressed the panes of structural glass, causing them to warp.
Actually though, your're right about the "self portrait"- there was only one spot to stand where there was almost no reflection of the photographer...
