Get your entirely legitimate, entirely free copy of Poser 5 here. You just have to register for the site (they're not spammy) and download. You have until sept 8th to comply.
Even if you're not really interested in all that 3D stuff you owe it to yourself to get it if you're even remotely artistically inclined. Many people use it exclusively for making painting references by using the default characters like those wooden dolls without ever going near the other hundreds or thousands of possibilities.
Edit: Now... for some reason I can't add this item to my cart ( I wanted to get P5 for my mac ) so it might be worth trying again tomorrow or something if you can't do it now.
