You can create Paper Critters at a relatively new site, email the url of your creation, post it, and then write a description.
What are Paper Critters, you might ask? Well, they are things that sort of defy description. A picture is worth a thousand words, so you might want to go their site.
They also allow you to print-out and then put together a paper model of your creation.
I’ve placed the link on my Examples of Student Work page under Student Paper Critters.
