I think the parameters are a tad ill-defined.
'Arty' as in 'Arthouse'? meaning aesthetic and overall presentation?
or 'Arty' as in 'pretty'? meaning the most visually attractive?
If I had to guess, I'd say it's the former, in which I think Portal is perhaps out of place in the poll: yes, it had a great game mechanic, and the story and graphics certainly not only worked but fit well with the other elements very nicely, but Portal never really struck me as being unique, or as having a particularly prominent overarching aesthetic; once you got past the newness of the gameplay mechanic being pretty different than virtually every other first-person game ever, the look and the feel didn't depart too much from Half-Life.
Flower and Flow, and Mechanarium, along with even the Oddworld universe are a few games which strike me as being good examples of 'arty' as I imagine was intended in the poll. As to a game which I particularly like the art design and execution, Bioshock 1&2 both had pretty stunning Art Deco themes on a level of detail I've never really seen before...
But, yeah, it'd be helpful to clearly state what the question is referring to, else we could have a large number of arguments where people are actually talking about two different things.
... well, unless that's the whole point in the first place...
