How to have animated thumbnails within slider on front page or anwhere?

How do I add moving images to a slider similar to Unitheme (seasonal product section) - it isnt a video. Looks very native - maybe a gif?

In General I would love to have custom page for collections to look similar to their concept. Is that easily doable with default blocks and grid creation for thin theme?

Check out their video

Would love to create several different collection pages for certain product groups looking like that.

Can it be done with default blocks and added css?
