If there's one thing people like to do more than taking pictures with their smartphones, it's tinkering with those photos in some way. Numerous apps have sprung up over the last several years that allow you to use filters and special effects to transform your pictures, and it doesn't seem like the appetite for those tricks has been satisfied for all smartphone users just yet.
As evidence, consider the rise of Prisma. Originally released in June, the app has been steadily climbing the App Store charts since then, and is on the verge of breaking into the top 10 as of the time of this post. Prisma's calling card is turning regular photos into pseudo works of art, complete with effects that make it appear your images were painted.
