Those montevideo ones look very nice. Now about the "Boekentoren" (Book Tower),
here is the official site of the tower itself, and here's also a picture

also,
here is a bird's eye view of the building (Bing Maps)
edit: You'll need to select bird's eye view yourself because it's unpossible to link directly into bird's eye view. If the weather permits (a lot of snow and -8°C predicted for tomorrow) I'll go and take some pictures.
second edit: Here's the first batch of pictures I went out to take







I hope these are somewhat useful to you, if you need more just tell me. Also if you need to know from where the pictures were taken (location in relation to the building), let me know. And, most importantly thanks a whole lot for doing this for me.
edit number 3: apperantly photobucked sized them down to 1024x768, if you want them in the original size, I can e-mail them to you
Take care,
Xander
