I'm starting to notice a few websites having the slider technique with images sliding in the slider. if that makes sense.

Following are some examples.

Web Design Sydney, Digital Agency Sydney, Digital Strategy - Adrenalin Media Sydney
Twofold Creative | Graphic, Print & Web Design in Brisbane

This one moves based on the mouse
Hotel in Tbilisi Georgia Holiday Inn

Does anyone know what the name of the technique is So i can look it up and learn

Thanks!
