Richard Schnoonover
He is always the one behind the lens in the Flickr stream. There is a reflection in the first photo that you included but that is of no use. This ain’t Blade Runner where you can just pan to one side and see what is behind something in a photo.
I think he is the guy who was wearing the steam punk top hat with all the LEGO bling glued to it at BF VA this year. I think he also makes a lot of skyscrapers. I could be wrong on both counts. Anyway, Tim definitely knows who he is.
