Made this one over the summer at my cottage. It took a long time because I made it in POV-Ray on my pentium II laptop and I only worked on it on and off. Test renders alone were taking half an hour. (And when you're working in POV-Ray, there you need a lot of test-renders to see what you're doing). The final render was done on my pentium 4 desktop though, because by that time I was home and I didn't want to wait days for a final Depth of Field render.
If you're unfamiliar with povray: it's not like 3ds max or maya or anything... you make the scenes by typing out code. This one ended up being 1000+ lines.
