Want to add some truly original characters to your e-learning or website? Take a look at the vector cartoon characters by GraphicMama. They can also customize characters (e.g., with company branding) or create new characters based on your needs.
I'm also impressed by the GraphicMama blog, "the place to read, learn, and get inspired by visual content, graphic design, and illustrations."
For example, here is a blog post with links to Free PowerPoint templates.
For anyone interested, I have a personal blog titled My Journey to Know the Savior where I share reflections about Jesus Christ.
