Free idea for a website or book
I was just wondering about the history of the filmstrip, but found little that was helpful on Google.
You know that would make for a good book or website. I'll bet that lots of us who went to school in the ancient era before Power Point might be intrigued by such an idea.
Perhaps Skip Elsheimer of A/V Geeks might wish to have a go at that. He has some filmstrips on his website that you can look at, and listen to.
