A while ago I was helping a client plan an open-riser modern staircase and railing. I collected these images for inspiration. This was long before I thought about starting a blog, so unfortunately I did not save any of the photo sources, but I want you all to be able to drool over them as much as I did anyway. If anyone really wants specific info on any of these I'd be willing to search around for its original source.
(I took this one. The stair material is 3-form, and it's awesome!)
