This one offers so many "Aha!" moments. There's a reason why this is a local favorite.

ANX: The Angle of Eternity

This puzzle made no sense for a long time, until the "Aha!" moment when it all came together.

Eel Trout

Another puzzle that made no sense for a long time, until the "Aha!" moment when it all came together.

Five a Day

This was the first puzzle cache I found that had a good "Aha!" moment, although it seemed more like an "ARRGH!" moment at the time.

Hit the Target

One "Aha!" moment came when I finally solved it, and another came when I realized what the solution implied about the puzzle design itself. It is truly elegant.

I kept over-thinking this one, until I finally had the "Aha!" moment when it all came together.

Minor Inconvenience

This is one of my favorite UncleTom puzzles. Many of his require solving a clearly presented puzzle. This one required an "Aha!" moment to see what the puzzle was.

Poetry Corner

I solved the multi-step puzzle correctly, but missed the hide. Then I re-thought and over-thought the puzzle, until I finally re-searched my original location more thoroughly and found it!

Rogue Ramblers' 45-Step Birthday Cache

This was one of my favorite puzzles. There was a big "Aha!" moment when I figured out how the pieces fit together, and many smaller "Aha!" moments as I figured out additional pieces.

Silicon Valley Treasure Hunt

This example of 4-star camouflage was my 666th find. It is an excellent example of a "good evil" hide. (A "bad evil" hide would be something like a needle-in-a-haystack hide.)

The Brink of Insanity

This "just show up" puzzle is one of my favorites. I completely missed it on my first attempt.

Tilted

The "Aha!" moment for this one came after I found and logged the cache, while I was reading the past logs. I suddenly understood how the owner had designed the cache, and that I had found it essentially by brute force. I wish I had found it as the owner had intended.

Tube It!

Each of these caches gave me a great "Aha!" moment, although they did it in various ways. (Many of these caches also demonstrate [url=http://www.geocaching.com/bookmarks/view.aspx?guid=2bc3b20d-b570-4e62-8c36-167990777982]Excellent Craftsmanship[/url], but I didn't want to include them on two public bookmark lists.)
