Here's an an older one from my workbooks. I've spent a lot of time exploring the possibilities for using various triads in improvisation. They create such strong lines and have a compelling internal logic an musicality.

These examples are pretty bare-bones, but there's a lot to work with.
The Augmented (aka symmetrical augmented) scale is made up of two augmented triads a half-step apart.
It works well over Maj7#5 chords built off the higher of the two triads (it implies a Maj7#5#9 chord). It also works over a dominant 7th chord built off the lower of the two triads (implies 13#5b9).
