I was also there yesterday around sunset. I'd agree completely with the comments made by dwntwnr on the feel of the memorial. One thing that concerned me was the impact of the ongoing development around the public space, however the size of the open areas is much larger than you can grasp from the webcams. I didn't feel constrained into a fenced in area and obviously the work is ongoing but it really didn't seem to intrude.
The pools are amazing. The size needs to be experienced. I could not see down to the bottom of the inner pool so it does feel bottomless. The bronze is so tactile you have to touch it. Your fingerprints fade over 30 seconds, it's eerie and melancholy when you notice that.
There were no waste bins (I didn't think there would be as security is tight and you have limited bags allowed in). Security were incredibly friendly (We had a stroller with us that had to go through x-ray - those guys were just great). I've been to other 'attractions' around the City and security were just rude - not here!
Finally as I left I noticed a police officer (there are many) touching a name on the pool. It really brings a lump to your throat... these names are in many cases all the physical connection available to real people, full lives lost. You do go from marveling at the spectacle to sadness in a heartbeat.
