First of all, great work on the site, very pleasing for the user and the eye.
I haven't been around for a while and I don't know what has been going on, so I assume the picture on the main page is a screenshot? Looks very nice, but the tower caught my eye. I wonder what impressions it has in addition to the base architecture of the kran? For it resembles my unofficial fan art challenge entry quite much (spikes on the top and the overall look):

I tried to find some information on the tower but find none, so could someone help me on this?
