I made a quick 2017 eclipse pinhole viewer/keepsake for everyone thats going to be hanging out with us during the event. Figured Id share the design if anyone here wants to make their own. I left some additional holes in it for fun. You can remove those if you dont want them.
Edit: if you are uninitiated, THESE ARE NOT FOR LOOKING AT THE SUN. use them to project the image onto a surface.
