Ansel Hsiao is both a big Star Wars fan and a talented 3D artist. Put them together and we get 3D models of Star Wars ships that are so detailed you could use them at a Corellian shipyard.
He concentrates on a selection of Imperial Ships (and one lesser-known Imperial Walker), so there are no computerised models of Mon Calamari Cruisers or X-Wings, but if you like Star Destroyers, then boy, he's got you covered.
To your left is a selection of his work, along with bare wireframe shots to give you an idea of the scale of the ships and vehicles.
Now if you'll excuse me, I have the sudden urge to go and play Tie Fighter again...
