I have been thinking about getting some extension tubes for years to try some micro photography. I finally did and they arrived today. They are great! (I made a homemade micro lens last year you may remember, by removing the front element off the front of an old lens, but it was not what I was hoping to use.)
So I got the tubes and threw them on some different lenses and pulled out a few flashes. The Christmas tree was there, so I had to try on it. Also a few coins on the table were easy pickings. (What would a micro test be without coins? )
I hope to find some more interesting subjects, but this was a good place to start today testing.
