Select a Background: First, click an image below to select a background. Ideally, the background would be similar to a scene with which you are already familiar. Be careful about clicking an thumbnail below before you've copied and saved a link to your work. The page will reload, and if you haven't saved your work, you'll lose your work (check directions below on how to save a link to your work).
Save your simulation: Right click your simulation and select "Save Image As." Type a name, and save the image to your local drive. Now it's yours and can be saved anywhere, but you agree to leave the logo intact.
Save or share your work: Copy the link below into a new browser tab. Bookmark it. Or, email it to yourself. Or, post it on a forum.
Directions: Drag and drop the ghost wherever you want it. Change the opacity slider to whatever you need.
