Ahh ancient history,,, one of ones many many fav topics
Saw those so called clever clogs from that show about" Busted" and all that
where POTUS Obama asked them to do it with mirrors..
Was sitting and kakin oneself as they tried,,but they missed the whole point
as they did not use the 'inside; of the 'shield design;,,
as in CONCAVE,,,
the doodles used flat surfaces,,,
,
Sheesh basic bush craft,,always carry a good convex lens in the go go car kit,,,
Makes KooKin tucker,, so much better that having to ruba dub some sticks,
