It's certainly "prettier" than Trello, but I'm not sure how functional it would actual be in a real world scenario. There's no functional benefit as far as I can see to putting things in fancy-looking circles, and (I'm imagining) the usability of that interface is severely diminished as you start to get a large number of items in any particular category.
A great example of how great UI doesn't necessarily equate to great UX, in my opinion.
