Mug

Pretty much, the most fluid animation work I have seen thus far. The amount of elaboration and detail to make liquid here is nothing I see a lot of these days. Watch these two shorts to see HD animation in action. 

An artistic piece. Where the story is as commendable as the literal presentation to respect. Puparia and Mug are not only such yet they are actually respectable art pieces. Would recommend both if you want something that has an elaborate fashion to be proud to flaunt about. 

Extremely fluid art is used to convey some kind of narrative. Could even go as far as to call it personification (more so in Mug). The animation carries a lot and equally offers an equal amount. 

A moving piece of art, one which is able to use art as a means to sincerely push forward their themes onto the viewer. You don't want to be missing out on some of the best their respective styles have to offer. 

Use of lines to convey the music, style, and idea of said anime in a fluent and sophisticated artistic way. Mug being flow, Orchestra being music. 

If you have watched Cat Soup, take this fluid body full of art, Mug, using its aesthetics to convey its sway as does the former. They are both time-efficient artworks made for those who want to see beauty.
