LiveQuartz

I have posted very briefly on BeLight's Image Tricks, Stone Design's iMaginator and Core Image Fun House and Quartz Composer but it seems there's something else to consider as an image editor and it's a freebie. Via Futurosity, I got to learn of Romain Piveteau's (RhapSoft) LiveQuartz 1.0.2.

Click here to see LiveQuartz at work. Looks like plenty of fun!

LiveQuartz is a simple image editor. It is based on layers and CoreImage filters.
You have the layers at the left and the filters at the right of the window.

LiveQuartz is localized in English, Chinese, German and French. ...
