Canvakala is a new plugin that allows you to do serious editing to your images without leaving wordpress. You can add effects like those in instagram, add text, brighten, sharpen, etc. There are even layers like in Photoshop. There are hundreds of images to pick from (you are pulling from sites that have legal images).  As I record this episode its $17 with a promise of the price going up (to what I'm not sure - you know the old internet marketing thing).
They do have a link to support which goes to a ticketing system, so without craeting a ticket, they have at least taken a step towards being legit. The plugin looks really cool. Here is the video demo.
