How color is used in visual storytelling.
Overview of this lesson.
In this video we will explore how perception plays a role in the colors we 'think' we see.
In this video you will visit our color suite to see how we tweak colors to meet artistic goals.
Learn how to write code that will add color and outlines to your drawings, using the JavaScript language and ProcessingJS library.
Introduction to color scripts.
This art history video discussion looks at the Colosseum (Amphitheatrum Flavium), c. 70-80 C.E., Rome.

Comparison of the processes of mitosis and meiosis. Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell. Mitosis involves one cell division, whereas meiosis involves two cell divisions.
Seeing how an inhibitor can "compete" for an enzyme with the intended substrate.
A closer look at the complex exponential term in Euler's Formula. We see that it represents a complex number, a distance of 1 from the origin of the complex plane. Created by Willy McAllister.
When we put time in the exponent of a complex exponential, the complex number it represent rotates in a circle on the complex plane. You can think of it as a spinning number! Created by Willy McAllister.
Complex numbers can be represented three ways on the complex plane: cartesian coordinates, radius and angle, and exponential form. Created by Willy McAllister.
Multiplying a real or complex number by the imaginary unit j corresponds to a rotation by +90 degrees. This is the key feature of j that makes it such a useful number. Created by Willy McAllister.
In this video we show you how and where to create the mounting holes in BIt-zee's Lexan base for the arduino, batteries, camera, on/off switch and wire routing. Created by Karl Wendt.
