googleing something like "building front view" will get u a bunch of stuff. You can pretty much get anything straight with the transform tool in Photshop though.
Here is a Mech that can transform down into a tank for the indie game Orion: Prelude. Just a quick start on the HP any and all comments are welcome :) I think i might redesign the front of the cockpit...
After seeing Transformers 3, I had to try and model the new girl, Rosie Huntington-Whiteley. She got some flak in the General Discussions thread here, but I don't care. I think she's beautiful. :) Just zbrush & polypaint.
Transform>Warp pretty much does that. Filter.Liquify too, but it's easy to get messy that way. Also, in your 3d app, you can project different uv layouts around, like a bendy mesh with straight uvs baked to your actual model.
