You can find a slightly more finished model here. 

There is another slightly different model of the main timbers in a cruck timber house, sometimes spelt crook timber house here. Again to see it you will need the free DirectorShockwave plug-in, a computer with at least basic 3d ability. The model is about 500Kb. 

When downloaded you can drag the model round with the mouse button, To move in other directions you can press shift, control or shift and control together, this last gives the freeest movement.  You can also zoom in and out with the up and down arrow keys, as well as moving left and right with the respective arrow keys. To reset press the F5 key, or in some browsers the Ctrl+F5 keys together.
