Free is always good. This site Glogster is just that free. But like all free site it want you to update to paid version. Well I was challenge by my student to make this site work. I had so much fun creating this interactive wall/poster to showcase my digital art students blogs/website. Please check out their links below. Then visit Glogster and share your creation with me. Can't wait to see.
