What's a good iOS app for messing around with photos and making 'em look...different? Like, not just filters, but kinda artsy?

Alright, so I downloaded this AIFilters thing 'cause I saw some kids using it. No BS, the tutorial is a waste of time. Just start poking around. It's got a bunch of filters, but not your usual garbage. Some of 'em make your photos look like paintings, others are just plain weird. I used it to make a picture of my truck look like it was out of some sci-fi movie. Pretty cool. The interface ain't exactly built like a brick house, but it gets the job done. Only real complaint is the battery drain. Eats through it faster than my crew goes through coffee on a Monday morning. Still, if you need to kill some time on a job site waiting for concrete to dry, it's worth a shot. Just bring a charger.
