i saw some "dancing " "rotating" "spinning" factory or starport or barracks while floating, also saw probes do the spinning also. how did they do that?

yes! but i haven't reach that mission, saw that from some video, it's very hidden. a place full of lava.

Optimus Prime (rosak but added booster jet) in Campaign Level 1

I've clicked on a lot of Thors in my time with Starcraft II, but I've never heard one talk back to me like this one does at around the 1:00 mark.

Actually, I've never heard half this stuff - only endless repetitions of IM HEAVY METAAHL - so thank you, Starcraft tinkerers, for unleashing the game's best unit and showing it in its best light.

Those who haven't seen it, or aren't familiar with it, the line is perhaps the greatest ever uttered in motion picture history.

Female Night Elf dancing beside Tosh, at the Cantina of Hyperion

Yup... if u talk to Tosh at some point of game, he is either facing his back to the wall or the Female Night Elf hologram. Can see much clearer then..

I heard somewhere on the net that if you click repeatedly on a non-playable creature on the map, it will explode ... also, like in the previous SC, if you left-click repeatedly on a particular unit, u will hear different dialogue and action on the preview screen ... heck, some of them are even cussing!
