My Citrix, VMware and Microsoft (app-v) Blender art

Several people have asked me where the many great pictures come from and how they can use it. Do you like my Bleder rendered App-V, Citrix and VMware Blog art?
The use of the high-resolution images in your "technical" blogpost and (or) parts of the pictures is allowed, if you place two backlinks to my blogs

http://www.Software-Virtualisierung.de"

and

http://www.andreasnick.com (coming soon, a completely English blog).

It is not allowed to use the images outside of a “technical” blogs. Here are the pictures in (different) high resolution ("Save As" to get the full resolution ).
