My PC had a total failure, when I was asked for a picture for the topic "robots & spaceships". Thus large parts of the 3D-models have been developed on a 1,1 Ghz Athlon. Fortunately my 2,8 Ghz Pentium was back for Rendering. Nevertheless, both the rendering and the postproduction were extremely time consuming - that I was able to finished it within 2 weeks is a small miracle. All 3D-models are actually very simply. But the many connected forms made working on them frustratingly boring, particularly with the model of the bird. However, after this model was finished, I could again become enthusiastic for the remaining work on the picture.
