I've been addicted to Prisma for a few days now. It's sort of like Topaz Impression for your phone, but without nearly as much control. You essentially have these filters which turn a photograph into drawn art. Here are a few examples.... Now, of course this sort of thing isn't for everyone, but I've been enjoying the process of creating these art pieces from photos I've taken. If you're a Prisma user feel free to share some of your photos in the thread.
