A stainless steel grate. Looks more like an illustration then a photograph, and it has a strange perspective that messes with your eyes. Are you looking up or looking down upon it?
Jakarta is an amazingly modern city - there are a lot of potential images like this there. Unfortunately, my experience is that it is not conducive to just walking around.
Nice image. Looking at it, it seems your looking up, but judging by what looks to be water droplets (top and left), the image is upside down
yes it does indeed mess with my eyes. I like it.
