I just couldn't resist adding my $.02 worth here. I really enjoy using it. The idea of taking a virtual trip at will while on the computer is a great idea. I think it gives a whole new perspective to my images as well. There's something strangely unique about seeing my own artwork hanging in a gallery of my choice. I especially like seeing it in unexpected locations, for instance, on Mars. The fact that it's free is absolutely incredible. I don't think you could buy anything close to this even if you wanted to. Do you get the idea, I'm a big fan?
