This is so incredibly cool.
For one moment I had to stop to figure what it was... and for one split sec I thought it was a deposit room with concrete floor, containing an old chest full of hay or some other dry crop... all this framed by a dark door, since you had taken the pic from a dark spot outside the room, using the back light that came through the window.
Yes, all that in one split second, until I realized it was just a brush. But, damn... a very well photographed brush!
Amazing shot, really. Went right to the top of my wish list - both "to have it on my wall" and "to photograph like this one day" wish lists ;)
