Stamps - Sundials

They make stamps with the coolest images.  Here is a set of sundial stamps I bought on ebay.  I love sundials.  I love the idea of using a stick and string to tell time.  I love some of the later sundials even more - metals ones, string and paper ones...  Some are so beautifully crafted it's incredible.  While I love the convenience - and accuracy - of watches and clocks, I still think sundials are petty cool.
