It would be wonderful if other towns appropriated this idea and recreated paintings that resonate with local landmarks. Austin would need something altogether weirder. With this summer's heat I keep thinking of Dalí's sun-blasted landscapes although Austin doesn't look much like that. I suppose one could half-recreate Le déjeuner sur l'herbe at Barton Springs (or more fully at Hippie Hollow). Any more geographically apt candidates?
