The current brushes and textures that we use on photoshop are static. It is one texture or shape simply repeated. Here I have tried to simulate the brush, canvas and paint in real time. The color mixing is Additive. The project is still in development and will be out for download soon.
Made using Java on processing with PixelFLow library.
