Plain boring glass, with colour, and a pattern which often makes a picture.Uhm, i got something like that in my entry, allthough its not really a picture, its more like a mosaic, you know.
I see myself standing little change.Lets face it dude, your entry was'nt about glass at all. Hmmm, only 2 windows, and a dolphin model, nothing more. Allthough, i must say that the dolphin looks really nice! Good job on that. ;D
