The first 3D model I made was a Dalek in povray (see povdal.jpg below), when I moved on to 3D studio a Dalek was the first model I made again. Because it is relatively easy to make, I found it was a good model to make to learn a new software package. There are several versions at the moment, 60's and 70's television ones, some 1960's film versions, and one from the 1960's comic strips and dalek books.

A 3ds model of the tardis was sent to me by Christopher Gill, I was so impressed at how realistic it looked that I took the surface maps from his model and used it on mine. In the picture of the 3 tardis below, the one on the left is by Christopher Gill, the one on the right is my original model, and the one in the middle is mine re-worked with the tif files from Christopher's model.
Here are a few pictures of my new dalek design. You may note that it has elements from the comic book daleks.
