Google sketchup (free) and the pro Sketchup are fast and easy for anyone to learn, they are excellent resources to have under your belt for quickly creating some creative works.

Sketchup is an amazing program. If you don`t know what it is check out the tutorials and WATCH that first segement when you “launch the tutorial” it will go over some of the ease of use and “wow” factor involved in this program that google bought and is giving away.
One of the example images is here:


and here is one I made myself (for a game I am creating) and it took me all of about 15 minutes

A person who has never used this program can quickly model their house/apartment in probably thirty minutes (from install to finished picture, though some of the details would not be perfect, but …)

one of the things that google added was the 3d warehouse in which users can share their sketches and easily import other sketches into sketchup..

For a programmer trying to do some base graphics or even finished graphics and who does not really know a lot about computer graphics it comes HIGHLY recommended..

I will post more on the game I am developing jointly with some other people as I get some beta work done on it, but I am just so happy with sketchup I wanted to post here about it.
