Best use of environmental manipulation in combat?

Sometimes a force user will think outside of the box when fighting an opponent, and use the area that surrounds him to his advantage. What are some of your favorite examples of a Jedi or Sith manipulating weather/droids to fight for him? Did he utilize it on a large number of droids to turn on their masters, or did he use alter environment for stealth purposes?

Luke used this technique to instantly turn off a bunch of droids.
Callista temporarily merged her consciousness with a ship or something.
Luke and Kyp's black hole feats were really cool.
There was this really brief line in LotF: Invincible where Luke just tosses a shuttle at a squad by glancing at it, I thought that was cool because of how casual it was.

Revan calling on HK to save his ass in ToS.

Jacen also pulled some Vong traps on Luke.

Kyp one-shotting that Sith Leviathan, obviously.
