OmniSketch is a drawing tool that lets you use brushes to draw. Bring to life whatever comes to your mind with neat effects, from leaving dots all over the canvas that grow bigger the faster you draw to crosshatching spaces between lines. If you’re not sure what your masterpiece looks like in the end, it’s probably for the best. The whole idea of drawing here lies in the abstract, which is fun considering the crazy effects you get with every stroke!
