He is professor of visualisation at the School of Computer Science and Electronic Engineering, Bangor University, U.K. He leads the Visualization, Data, Modelling and Graphics Group (VDMG), leads project rainbow and is an author of the Springer book "Five Design-Sheets" sketching design method.
Think about your program before you code. This post goes through the five steps of the Critical Thinking Sheet.
This post starts you off with Processing. Download, run and draw some coloured lines. The computer programming language Processing, is a great way to start coding. You get a quick visual result from a few lines of code.
Learn RGB colour coding
Values of Red, Green and Blue colours are used to code colours on a computer. Learn how to create different colours from RGB values.
Rainbows and Colours
Understand rainbows, why we typically think it has 7 colours, and make a colour spinner.
