Astronomy with Pin and Paper

Ring of Fire, not so much...

Here in Minneapolis we were not on the path of today's annular eclipse.  But between the yard work and the house work we took time to observe the partial eclipse visible to us in Minnesota.  Not having any eclipse glasses on hand we pricked a pinhole in a piece of card board and projected the image on another.  Our implementation of the technique was neither high tech nor high rez, but it sufficed.
