How to Draw the Female Eye Step by Step
About Faith Graphite Pencil, Charcoal Pencil and Pastels Artist Hello! My name is Faith Te. When I was 16, a great desire to capture nature and the people around me started my passion for drawing. I began to look at drawing not just as a hobby but something which I wanted to do all my life. I practiced every day and for many hours since. Initially, charcoal and graphite pencils were the only mediums I used. I devote many hours and lots of attention to detail into each and every one of my drawings or paintings. Thank you for your interest in my artwork. Please take a moment to visit Faith’s Website and Blog to learn more about her and her products and services.

Harmonograph
A harmonograph output A harmonograph is a mechanical apparatus that employs pendulums to create a geometric image. The drawings created typically are Lissajous curves, or related drawings of greater complexity. A simple, so-called "lateral" harmonograph uses two pendulums to control the movement of a pen relative to a drawing surface. More complex harmonographs incorporate three or more pendulums or linked pendulums together (for example hanging one pendulum off another), or involve rotary motion in which one or more pendulums is mounted on gimbals to allow movement in any direction. A particular type of harmonograph, a pintograph, is based on the relative motion of two rotating disks, as illustrated in the links below. Computer-generated harmonograph figure[edit] A harmonograph creates its figures using the movements of damped pendulums. in which represents frequency, represent phase, represent amplitude, represents damping and represents time.

Zentangles: my new favourite artform | The Underground Artist Pub
I recently bought the book One Zentangle a Day from amazon and I’ve found it a lovely and practical introduction into the art of zentangles. This is a recently developed technique where you draw repetitive strokes over and over again, adding shading and highlights to form a patterned tile. These tiles can be shaped to create a greater picture or form. Below is a starter Zentangle that I drew recently. Here are some more advanced zentangles from the web. Why not give zentangling a go.
