I really like the Treebeard engine used in "Chess" and "Chess Free" for Android Devices. I like playing computers and this is one of the most human like engines I have ever tested. It makes very credible mistakes. Sometimes it plays well, sometimes it misses something.
The only thing I don't particularly like about the product is the GUI. It's clear that is designed for someone who just wants to play now and then, without getting bothering too much by complicated settings.
Not recommended for engine vs. engine play or strong human players above 2000 Elo, but perfect for patzers like me.
Just trying to compile a list of the engines that play in the most beautiful, positional, aggressive, human-like etc styles.
You guys are the experts...let me know if I've missed any.

Clearly I'm a guy who cares more for style than strength.
There are also a handful of personalities I am working on but still testing.
Have I missed any great current or historial engines in my list (which is in random order I should mention)?
I always enjoyed Gromit/Anaconda
Looks like the Anaconda link is broken from the author's site but found Gromit.
